Every US State’s Most Isolated Island (And Why People Live There)

[00:00:00]What would you do if you lived on an island so remote that the only way out in an emergency was a helicopter and your whole town was sinking into the sea a little more every year? What would you do if the government showed up with $48 million and told your community it was finally time to abandon the only home you had ever known? This is across the globe and today we're taking you to the single most isolated island in every US state. Let's get into it. Alabama Dolphin Island. 14 mi of sand guard the mouth of Alabama's Mobile Bay. Today, Dolphin Island is a bridgel linked paradise. But in 1979, Hurricane Frederick's 145 mph winds tore that bridge apart. For nearly 3 years, its 12200 residents were completely stranded, relying on nothing but boats and helicopters. But isolation is baked into this island's bones. In 1699, French explorers found the beaches littered with human skeletons that an earlier hurricane had dug up. Horrified, they named it Massacre Island. Alaska, St. George Island. Sitting 300 miles out in the Bearing Sea, St. George Island supports just 67 yearround residents.

[00:01:06]This isolated outpost, reachable only by a grueling flight from Anchorage is home to the Unangak people. Their ancestors were brutally forced here by Russian fur traders in the 1780s, and the US government later evacuated them to a grimy abandoned canery during World War II. Today, the island faces drastic wildlife shifts. While local furs seal numbers have dropped to around 500,000 across the region, more than 2.5 million nesting seabirds swarm the island's steep volcanic cliffs each summer. The people stay out of a fierce multi-generational duty, fighting to govern their own waters and protect their marine ecosystem. Arizona Lake Powell. The Grand Canyon State has no natural historically inhabited islands at all. But in 1963, engineers built the Glen Canyon Dam and drowned a massive red rock kingdom. As billions of gallons of water choked the canyons, towering sandstone peaks were cut off and turned into isolated boatonly islands. But the real story is what's under the water.

[00:02:05]Submerged under hundreds of feet are thousands of sacred ancient ancestral PBLO in ruins. Desperate salvage teams cataloged what they could. But today, severe climate droughts are causing these ghostly ruins to rise back up from their watery graves. Arkansas, Sugarloaf Mountain Island, floating in the western arm of Greer's Ferry Lake near Fairfield Bay. This landmark became an island in 1962 when rising reservoir water cut it off from the mainland. The peak towers 540 ft above the water. To conquer its steep sandstone bluffs, workers handcarved a wooden staircase wedged directly into vertical fractures in the rock. In 1963, President John F. Kennedy dedicated the nearby dam in one of his final public appearances just weeks before his assassination. Below the surface lie the submerged foundations of relocated towns, while the peak above holds the first national recreation trail in Arkansas, California, San Nicholas Island. Sitting 61 mi out, California's most isolated outpost is San Nicholas Island. Today, it's a restricted Navy weapons testing site, but its history holds a heartbreaking mystery. In 1835, the indigenous Nicoleno people were evacuated. Yet, one woman was accidentally left behind. She survived entirely alone for 18 years in a whale bone hut, even hand sewing a gown out of greenish feathers. When she was rescued in 1853 and brought to the mainland, her body couldn't handle the rich new food after years of seal fat, and she passed away of dysentery just 7 weeks later. Colorado Blue Mesa Reservoir. Colorado's largest body of water, Blue Mesa Reservoir, has several islands, but these aren't natural paradises. They're the flooded ridgetops of a drowned valley. The real story sits directly beneath the surface. In the 1960s, the government damned the Gunnison River, forcing the historic ranching town of Iola to evacuate. Homes were bulldozed, dynamited, and submerged under billions of gallons of water. And right now, severe droughts trigger an eerie thing. The reservoir drops and Iola climbs back into view. Coming up from the mud are old foundations, rusted tools, and a school flag pole still carrying the etched initials of longgone children. Connecticut. Money Island.

[00:04:14]Money Island is a 12acre granite outpost off the Stony Creek coast. It once supported a buzzing summer colony, but disaster struck during the catastrophic 1938 New England hurricane, which killed seven people here. The storm surge was so massive that several entire Victorian houses were lifted right off their foundations, intact, and floated out into Long Island Sound like ghost ships before they sank. Legend says Captain Kid buried treasure here and the region's famous pink granite used to build the bases of the Statue of Liberty and the Lincoln Memorial came from neighboring Bear Island and the nearby mainland. Delaware, Pea Patch Island.

[00:04:50]Legend claims Pea Patch Island sprouted from a colonial shipwreck spilled cargo of peas. Centuries later, this Delaware River mudflat became America's brutal water encircled Alcatraz. During the Civil War, the Union jammed 12,000 Confederate prisoners into filthy smalloxridden barracks here. Very few survived swimming the freezing, treacherous currents to escape. Because the island is low-lying and marshy, the thousands who died were boated across to mass graves in New Jersey. The screams are long gone now, but this strictly restricted sanctuary hosts the largest colony of nesting waiting birds north of Florida. Florida Eggmont K, a tropical paradise hides a horrific secret at the mouth of Tampa Bay. Eggmont Ki has zero public restrooms and no drinking water, leaving park ranger Mr. Tom as its only permanent resident. He patrols the brick paved streets of Fort Dade, a Spanishamean war ghost town being actively swallowed by the ocean. But the island's darkest era centers on the 1858 lighthouse. Here, the US Army built a brutal camp, caging hundreds of captured Seol women and children before forcing them onto westbound deathboats. The survivors still remember this island as the dark place. Georgia, Sapalo Island.

[00:06:03]Generations of enslaved West Africans fought to keep Sapalo Island's hog hammock alive. One of the last intact saltwater gei communities on Earth.

[00:06:12]Today, fewer than 50 residents are left battling harsh zoning laws and skyrocketing property taxes designed to push them off their ancestral land. The island's kids even have to ferry to the mainland every day just to get to school. And on October 19th, 2024, during a celebration of Gulagichi culture, the island's aluminum gangway collapsed as crowds were leaving by ferry. Seven people, most of them elderly visitors who'd come for the festival, were killed, a tragedy that exposed decades of neglect. Here's the wildest part. The Golagichi built their community out of tabby, a tough coastal concrete made from oyster shells that has outlasted hurricanes and time itself. Hawaii Nihao, 17 mi southwest of Kauaii, Nihow has been privately owned by the Robinson family since 1864 when Elizabeth Sinclair bought it from King Kamehahha V for $10,000 in gold. With an estimated 70 to 130 residents, the count fluctuates. Its people live without paved roads, public electricity, or running water, getting around on horses and bicycles, and collecting rainwater.

[00:07:16]Nihow is the only place where Hawaiian is spoken as the daily language, and its emergency helicopter used for medical evacuations, is the exact same aircraft featured as the inen helicopter in the 1993 Jurassic Park, Idaho. Pearl Island, Lake Pere. Deep inside Idaho's 1100 foot glacier cararved abyss, Lake Pere hides a strange mix of elite wealth and military secrets. Reachable only by boat, the island of Pearl was homesteaded in 1907, while nearby Warren Island was scooped up by an Annheiser bush tycoon for a luxury resort. But the real mystery is beneath these isolated shores. The US Navy uses this pitch black freshwater void to test top secret stealth technology. Here they run the Cocon, a massive 90tonon quarter scale unmanned submarine that glides silently through the deep, perfectly mimicking a real nuclear vessel. Illinois Plum Island. The prairie state's most isolated river island is Plum Island.

[00:08:13]Sitting in the Illinois River near starved rock. Once a recreation spot in the early 1900s, it's now a protected bald eagle sanctuary. Illinois has a more famous island story, Casasia, the state's original capital, which was cut off by a flood in 1881. But Plum Island is the quieter side of Illinois geography. It's a place where people once came, then left, and that's now watched over by soaring birds. You can't set foot on the island itself, but you can easily catch a view of it from the overlooks of neighboring Starved Rock State Park. Indiana Wabash River Islands. Most people think Indiana's flat, landlocked geography has no isolated island communities. They're wrong. Right at the treacherous meeting point of the Wobbash and Eel Rivers sits Bidd Island, this isolated 17acre patch of land is permanently inhabited, supporting 20 brave residents who build their homes directly over the rushing currents. Founded by an eccentric 19th century judge who built a private mansion kingdom here, island life is a beautiful gamble. Whenever severe Midwestern floods strike, the Lone Bridge disappears underwater, stranding this hidden neighborhood in the middle of a raging river. Iowa, Sabula. As Iowa's only island town, Sabula sits in the Mississippi River, about a mile long and a/4 mile wide with 506 residents as of 2020. But it wasn't always an island.

[00:09:31]In 1939, the Army Corps of Engineers flooded the nearby lands with lock and dam number 13, ringing the town with water. Founded in 1835, legend says the first settler floated over from Illinois on a log. Once home to a clamshell button and comb factory, Sabula is now linked to the mainland by a causeway and a 2017 bridge. Its beaches still turn up antique clamshells riddled with holes from the old factory. Kansas Milford Lake. Kansas's largest reservoir, Milford Lake, has no inhabited islands, but it does hide a drowned town called Brotton. Before the lake filled between 1962 and 1967, this place had two railroads, a stockyard, a grain elevator, a post office, a school, a church, and a general store. Then in 1966, government bulldozers flattened it. While some folks claim Broton's Mexican railroad workers grew illegal marijuana, the historical record points more to the wild ditch hemp that once grew all over the area. Now, former residents gather every year for a reunion, and a white marble monument marks where their childhood homes once stood. Kentucky, Wolf Island. In the late 1700s, river travelers terrified of predators named this Mississippi River land mass Wolf Island. By 1799, it became a lawless stronghold for Samuel Mason's brutal gang of river pirates.

[00:10:49]Missouri sued for the land, but an 1870 Supreme Court case awarded it to Kentucky after the court compared the island's soil and trees to Kucky's mainland. Over time, the river shifted course completely, physically fusing the old island to the western riverbank.

[00:11:03]Unbelievably, this created a bizarre geographic quirk, the only place in America where you can drive directly into Kentucky on a Missouri dirt road.

[00:11:12]Louisiana, Eel Deja Charles. Since the 1830s, this eel deja Charles band of Belaluxy Chidamacha Chakta has called this island home. At its peak in 1955, it spanned over 22,000 acres, but only about 320 acres remain. Erosion, subsidance, and rising seas have claimed 98% of the land in less than 70 years.

[00:11:34]The population, once around 300 families, has dwindled to roughly 26 residents. In 2016, Louisiana received $48.3 million for a federally funded climate relocation, moving the community 40 mi north. The island's only road built in 1953, sits so low it floods constantly, turning every trip into a gamble. Maine Matinus Isle, 20 mi out to sea, Maine's Matinus Isle is the east coast's most remote, unapologetically lawless frontier. Maritime guides once labeled its fiercely guarded waters a hostile harbor thanks to aggressive territory protecting lobstermen. On land, 50 residents get by without restaurants or public restrooms. Their tiny town library actively fights mainland censorship by deliberately stalking banned books. This extreme isolation has bred a stubborn streak of independence going all the way back to 1757 when indigenous warriors killed the island's first illegal squatter. It's a place so distinct that by tradition, elderly locals refused to ever leave until they were boated away to be embaled. Maryland. Smith Island. Cradled by the volatile tides of the Chesapeake Bay, Smith Island is actively drowning.

[00:12:45]With zero bridges to the mainland, this eroding cluster of land is projected to disappear completely by 2100. Yet, when the government offered massive buyout checks to relocate everyone, the local watermen flatly refused. They still work these waters, speaking a distinct English dialect that's gone basically unchanged since the 1600s. Their multi-generation population is fading, symbolized by their lone school closing after enrollment hit zero. But their legacy survives in a multi-layered cake originally engineered to last weeks on freezing crabboats without spoiling.

[00:13:18]Massachusetts Thatcher Island about a mile off Rockport. Thatcher Island covers around 50 acres and holds the only operating twin light station in the US. Two lighouses first lit in 1771.

[00:13:31]Reachable only by boat, the island is maintained by a town association and the US Fish and Wildlife Service with seasonal stewards living in the keeper quarters. It's named for Anthony Thatcher, who survived a 1635 storm that killed his four children and was granted the island as compensation. The twin lights were a clever navigation trick.

[00:13:49]Ships out on the Atlantic could tell these dangerous rocks apart from every other light by spotting two side by side. Michigan is Royale. Isolated in the freezing depths of Lake Superior is Isisle Royale, the most cut off wilderness in the lower 48's national parks. This roadless 200 square mile archipelago completely empties out and closes every winter, leaving the island to a famous decadesl long ecological drama. isolated packs of wolves hunting moose herds across a sealed off ecosystem. Decades ago, Scandinavian fishing families held life leases here.

[00:14:23]Today, it's a protected fortress with over 99% of its land mass legally designated as federal wilderness. The only way to reach its rugged shores is a multi-hour ferry crossing right over a graveyard of sunken shipwrecks.

[00:14:36]Minnesota. Malard Island. Covering just 1.5 acres in Rainy Lake, Malard Island sits a mile south of the Canadian border. It was home to conservationist Ernest Oberholtzer from 1922 until his death in 1977. He chose this island over larger ones because the Ojiway believed its spirits were especially strong.

[00:14:55]Oberholtzer led the campaign behind the 1930 shipstead Newton Nolan Act which established the wilderness protections that laid the foundation for the Boundary Waters Canoe Area. The Ojiway called him Atisokan, meaning legend or storyteller. After he died, they reportedly placed a protective spell over the island, preserving his review house, which holds over 11,000 rare books, turning the tiny island into a floating library in the wilderness.

[00:15:20]Mississippi cat island. French explorers originally named Mississippi's T-shaped Cat Island after mistaking its native raccoons for feral cats. For generations, a Spanish pioneer dynasty ruled this isolated land. But during World War II, it hosted a horrifying top-secret military experiment.

[00:15:38]Believing a racist theory that ancestry dictated human scent, the US Army forced Japanese American GIS to dress in padded gear and act as live human bait to train vicious attack dogs. The experiment failed miserably when the dogs just licked the soldiers. Today, this empty island is a quiet coastal preserve, slowly reclaiming its dark secrets.

[00:16:00]Missouri, Lake of the Ozarks. Missouri's serpentine lake of the Ozarks has more shoreline than the entire coast of California. Yet, it features zero paradise islands. Instead, this liquid fortress seals away a drowned society.

[00:16:14]When the massive Bagnell Dam closed in 1931, it flooded the historic valley and swallowed eight entire towns. Among them was Lin Creek, a bustling county seat whose residents were forced to bulldoze and burn their own homes before the water came. Today, 50 ft beneath the speedboats and vacationers lies a silent cemetery of stone foundations, forgotten fences, and a massive steel highway bridge dropped straight into the depths.

[00:16:39]Montana Wild Horse Island. Wild Horse Island, the largest in Flathead Lake at 2,160 acres, is the biggest island in a freshwater lake west of Minnesota.

[00:16:50]Reachable by a 25-minute boat ride from Big Arm, it's a place where the Salish Coupin pastured horses for centuries, using the water as a natural barrier against rival tribes. Homesteaders cleared the old growth forest between 1910 and 1915, leaving behind a cabin that still stands today. Now, wild horses, big horn sheep, and century old orchards all thrive among the leftovers of its storied past. Nebraska, Lake McConna. In Nebraska's sand hills, the massive Kingsley Dam seals away a drowned empire. Reinforced by 180,000 giant 800-lb concrete jacks, this wall permanently swallowed the town of Le Moine. The reservoir has no natural islands, but severe droughts force a haunting resurrection. When the waterline plummeted, the lost town reemerged from the mud. One elderly survivor managed to map his childhood streets entirely by finding a single rusted Schlitz beer can sitting on his old pool hall's foundation. Speedboats now cruise right over these ruins.

[00:17:46]Inches away from a terrifying 10-story tall morning glory whirlpool drain.

[00:17:51]Nevada. Anaho Island. Hidden deep in Nevada's high desert basin, a jagged 200 acre tufa mountain rises from the blue water of Pyramid Lake. This is Anaho Island. Sacred to the Pyute tribe for thousands of years. It's so protected that boats are legally banned from coming within a thousand ft of its shores. In 1913, President Woodro Wilson used federal law to lock this predator-free rock down as a strict wildlife sanctuary. Every spring, 10,000 American white pelicans swarm the island to breed, temporarily growing bizarre prehistoric looking horns on their glowing orange beaks before launching 100m nightly commutes to hunt for food.

[00:18:30]New Hampshire Star Island. 7 mi off Portsouth, Star Island covers 38 acres out in the open ocean. It holds the historic 1873 Oceanic Hotel and the ghost of Gosport, once a busy fishing port chartered in 1715 with about 600 colonists. Most residents were evacuated in 1776 over revolutionary war fears. In 1915, the island was sold to a religious group and today it runs the largest off-grid solar farm in New England. Long ago, carrier pigeons were the island's lifeline. They deliver lunch orders from the mainland ferry so chefs could prep fresh Atlantic cod. You can still see the original pigeon cages inside the island's museum. New Jersey. Burlington Island. In the Delaware River, the overgrown wilderness of Burlington Island holds some of New Jerseys oldest secrets. In 1624, Belgian pioneers built the state's first European trading post here, which later became the site of New Jerseys first recorded murder in 1671.

[00:19:29]Centuries later, a trust fund locked down the island's rental profits, funding America's longest continuously operating public school trust. After a roaring 1920s amusement park burned to the ground, sand miners carved a massive 100acre lagoon into its center. Today, this empty island is a protected fortress where wild bald eagles nest above the sunken ruins of an old roller coaster. New Mexico elephant but the volcanic core of New Mexico's elephant but was named purely for its shape long before anyone knew actual prehistoric monsters lay buried right beside it in 1916. This project formed what was then the largest man-made lake in the world permanently drowning the railway lines, hospitals and construction camps of,200 laborers. Today their stone foundations rest silently on the reservoir floor.

[00:20:16]The island has never had permanent residents, but history exploded here in 2014 when a lakeside bachelor party stumbled onto a 3 million-year-old stega mastadon skull. Now near record droughts routinely drain the basin, turning this historic island into a desert peninsula.

[00:20:32]New York. Fischer Island. Legally belonging to New York, but sitting 2 miles off Connecticut, Fischer Island has America's ultimate administrative identity crisis. This 9mm stronghold of old money wealth uses a Connecticut zip code, a New York area code, and ships its trash to Connecticut landfills.

[00:20:50]There are zero fairies to New York. And if state troopers need to respond to an emergency, they have to drive a 100 miles through Connecticut just to catch a boat. In 2004, frustrated islanders even launched an official campaign to secede from New York entirely, trying to escape a state they can't physically reach. North Carolina. Portsouth Island.

[00:21:10]Founded in 1753, Portsouth Island was once the largest settlement on the Outer Banks with nearly 700 residents by 1860.

[00:21:18]It was a hub for North Carolina's imports with 2/3 of them passing through nearby Okra Coke Inlet. But an 1846 hurricane carved out new inlets, rerouting the shipping lanes and starting a slow decline. By 1956, only 17 residents were left. And the last two, both elderly women, left in 1971 after the death of Henry Pigot, their beloved caretaker. The National Park Service now preserves about 21 historic buildings, including a church, a school, and a lighthouse, all frozen in time.

[00:21:48]North Dakota, Graham's Island. The Peace Garden State's 9 square mile Grahams Island is trapped inside Devil's Lake, a closed terminal basin with no natural river outlets. Water only escapes by evaporation, triggering violent centuries long cycles where the lake either quadruples in size or dries up entirely. Because of this, Graham's Island constantly shifts between being a true island, a peninsula, and a dry hilltop. Long ago, a prophetic tribal dream drove the Hata away from this volatile basin. Centuries later, the lake swelled so violently that it swallowed the roads. Today, engineers maintain a massive four-mile Earth & Causeway just to keep this shape-shifting fortress reachable. Ohio, North Bass Island, 18 miles from Ohio's mainland and just under 2 mi from Canada, North Bass Island covers 688 acres with only a handful of residents and over a dozen empty houses. It's the one Ohio island with no ferry service.

[00:22:43]You get there by private plane or boat, and ICE covers it for 4 months a year.

[00:22:48]Once home to Ohio's last one room public school, which closed in 2005, its high school students now fly to the mainland for class. The island's 38 least acres host a winery that keeps its grape growing heritage alive, and the people who stayed feel incredibly safe. Crime is so rare that the historic island church stays unlocked day and night.

[00:23:08]Oklahoma. Lake Texoma. Landlocked Oklahoma hides a massive saltwater paradox. Deep within Lake Texoma, a prehistoric underground sea deposit relentlessly dumps 3,450 tons of salt into the basin every day.

[00:23:22]This bizarre brine actually lets ocean native striped bass spawn naturally thousands of miles from any coast. But the lakes's true secrets are locked below. During World War II, the military forced captured German prisoners from Raml's elite Africa Corps to hand clear this valley. To stop escapes, the men wore blue denim uniforms with the giant letters PW painted down their legs in glowing white oil paint. Speedboats now zip right over their sunken history.

[00:23:48]Oregon. Savvi Island. Sitting 10 mi northwest of Portland, Savvi Island is a river outpost home to 1,000 residents.

[00:23:56]Centuries ago, it supported over 2,000 Malttoma people before a devastating 1829 epidemic nearly wiped them out. The island also holds a bold piece of pioneer history. Defiant settlers illegally logged Svi Island's ancient timber to build the Star of Oregon, a 53- foot vessel, they sailed to California to trade for cattle.

[00:24:16]Successfully shattering a ruthless British corporate monopoly. Reachable only by ferry until 1950, this farming community still feels completely removed from the city next door, Pennsylvania.

[00:24:27]Three Mile Island. Pennsylvania has no isolated island communities, but its most infamous river outpost is 3M Island. In March 1979, the site suffered a partial nuclear meltdown at Unit 2.

[00:24:39]That broken reactor never reopened, but a shocking modern twist is unfolding.

[00:24:44]Constellation Energy and Microsoft signed a 20-year deal to fully resurrect the undamaged Unit One reactor, now accelerated for a 2027 restart. Renamed the Crane Clean Energy Center, it'll pump 835 megawatts of power directly into artificial intelligence data centers. And long before any nuclear power, this river landmark held Native American campsites dating back thousands of years. Rhode Island Prudence Island Naragansit Bay's 5 square mile Prudence Island has zero hotels, restaurants, bars, or traffic lights. Its original tribal name translates to a place apart, a trait proudly protected by its 150 yearround residents. They rely on Rhode Island's last active one room schoolhouse, which recently held a graduation ceremony for a single student. Why do these families choose to live so aggressively cut off? To wage a quiet revolt against modern commercialism. They stay to protect a slow lifestyle where dirt roads replace gridlock and where roaming herds of wild white-tailed deer actually outnumber the people. South Carolina. Sandy Island.

[00:25:47]Trapped between two rivers, Sandy Island is home to 50 Golagichi residents living with zero bridges to the mainland. Every morning, the children board the state's only public schoolboat. These families stay to honor an unbroken chain of post-slavery triumph, acting as cultural sentinels protecting their West African blended language and heritage. Their isolation is reinforced by federal law.

[00:26:08]The island's nature preserve protects the rare red cockaded woodpecker. And because those birds need living 80-year-old longleaf pines to nest in, strict habitat rules keep modern roads from ever slicing through the canopy.

[00:26:20]South Dakota, Lake Oah. South Dakota's Lake Oah has no inhabited islands, but this 231 mile reservoir holds a devastating history of displacement.

[00:26:30]Created between 1948 and 1962, the rising water flooded over 200,000 acres of suland, drowning towns, and sacred burial grounds. Before the flooding, the federal government rushed to relocate cemeteries, but ignored tribal elders about historic unmarked graves. As a result, the rising water aggressively eroded human remains and ancient burial goods straight out of the clay banks that triggered decades of agonizing recovery efforts by tribal preservation offices trying to protect their ancestors. Tennessee Norris Lake created in 1936 by Norris Dam, Tennessee's Norris Lake completely drowned the historic town of Lyon. The massive project displaced nearly 3,000 families and forced the state to carefully dig up and move 5,056 graves out of the valley floor. To capture this disappearing Appalachian world, the TVA hired legendary documentary photographer Lewis Hine in 1933, though he only got through roughly 197 families before being dismissed. Today, the submerged town site is known as the Loyon Sea. And beneath nearby Telico Lake lies another lost capital, Chota and Tanis, the historic Cherokee town that gave Tennessee its name, Texas. Madagorta Island. Texas's 38-mile Madagorta Island has zero permanent residence. A wilderness strictly enforced to shield the planet's rarest endangered whooping cranes. People are barred, leaving nature to consume a bizarre military graveyard. Here, a cast iron 1852 lighthouse stands amid an abandoned World War II airfield that Cold War bomber crews later used for practice bombing runs. Just offshore lies Indianola, a drowned ghost town of 5,000 people erased by back-to-back hurricanes in 1875 and 1886. And it was on these exact shores that the US military once landed two ship loads of camels for a deeply strange pre-Ivil War desert warfare experiment. Utah. Fremont Island. Spanning nearly 3,000 acres in the Great Salt Lake, Fremont Island is reached by a grueling 6 to seven mile muddy sandbar crossing. In 1843, explorer John C. Fremont named it Disappointment Island, while Kit Carson carved a rock cross that still remains today. Later in 1862, Brigham Young exiled a grave robber here who had desecrated roughly 300 graves. And the man later slipped away on a makeshift raft, never to be seen again. The state acquired the land in late 2020 after a philanthropist blocked developers from building a 12,000 unit luxury mega city on the island, which has no water, electricity, or sewer infrastructure at all. Vermont. Burton Island. Floating inside Lake Champlain, Vermont's 200 acre Burton Island bans all cars.

[00:29:12]Reached by a passenger only ferry, this state park has zero permanent residents.

[00:29:16]For over a century, pioneers ran a massive dairy farm here, leaving old stone walls widening through the forests. The state originally planned a permanent vehicle causeway, but deliberately scrapped the blueprints to save the island's raw isolation. So why does it stay completely empty today? To enforce a strict acoustic sanctuary, a quiet, motor-free world where handpulled wagons replace traffic and only winter campers brave the frozen lake. Virginia, Watts Island. In Virginia's Chesapeake Bay, a rapidly dissolving sliver of land called Watts Island loses an entire acre to the ocean every single year. Once a 1600 stronghold for tobacco rating pirates, the island was cut in half by a 1908 storm, driving out all its traditional families. 2 years later, a Princeton educated lawyer claimed the empty rock on a 10-year bet, living as a hermit for nearly three decades. Today, its historic lighthouse lies completely underwater. The federal government keeps this drowning fortress strictly off limits to the public, preserving a quiet, predator-free sanctuary for one of Virginia's largest nesting bird colonies. Washington, Smith Island.

[00:30:24]Sitting 5 miles out in the straight of Wand Fuca, Smith Island is a disappearing 15 acre wildlife refuge.

[00:30:30]Its steep bluffs erode 20 ft per decade, a process that sent its historic 1858 lighthouse plunging into the sea in 1998. During the Cold War, the Navy weaponized this isolation, locking down a restricted target range to monitor secret acoustic torpedo tests. That heavy military shield legally barred outside ships, which let Washington's largest underwater forest of bull kelp grow completely untouched. Today, it's home to feral rabbits and the state's last major inland tufted puffin colony.

[00:31:00]West Virginia, Blenerassid Island.

[00:31:03]Anchored in the Ohio River, West Virginia's Blenerhassid Island once hid the headquarters of a dangerous domestic conspiracy. In 1798, an Irish aristocrat built a grand mansion here, which former Vice President Aaron Burr hijacked in 1805 to launch a rogue military plot to carve out his own private Western Empire. President Jefferson sent troops to crush the treasonous staging ground.

[00:31:26]Today, a meticulous reproduction of the mansion stands over the ashes. Built between 1984 and 1988 before opening for public tours. Now a preserved state park, this unpopulated island once also sheltered outlaws running prohibition moonshine stills. Wisconsin. Sand Island. In Wisconsin's Apostle Islands, Sand Island once held a Scandinavian community of 70 residents before the last families left. To show just how isolated it was, a lighthouse keeper journal from November 1898 records that his neighbors had completely lost track of time with no idea what the day or date even was. Later, an underwater telephone cable connected the island to the mainland in 1918, and the very first message it carried announced the end of World War I. When the cable broke, families went back to lighting shore bonfires to signal for boats. The lighthouse was automated in 1921.

[00:32:19]Wyoming. Frank Island. Marooned in Wyoming's subalpine wilderness, Yellowstone Lake's massive Frank Island holds a fragile ecological timeline.
