Bannock County: The Robber’s Roost Gold
The year 1865 marked a daring stagecoach robbery in Bannock County, where a staggering 300 pounds of gold were pilfered from its rightful owners. According to local lore, the audacious bandits, with a posse hot on their trail, hastily buried their colossal loot approximately three-quarters of a mile north of the small town of McCammon, at a site now infamously known as Robber’s Roost. Their escape was short-lived; the lawmen quickly caught up, leading to a fierce gunfight that ended with the deaths of all the robbers. Tragically for the authorities and hopeful treasure seekers, the stolen gold was never recovered. For over a century and a half, this substantial treasure has remained hidden, an enduring mystery of Bannock County, tempting those who believe they can crack the secret of its location near Robber’s Roost.
Boise County: Golden Riches of the Basin and Rye Flats
The Abundant Boise Basin
Boise County, particularly the vast Boise Basin, has historically been a mecca for gold prospectors. Close to three million troy ounces of gold have already been extracted from its gravels, yet treasure hunters firmly believe that a substantial amount still lies hidden within its rich earth. The prime areas for exploration are often cited as the numerous watercourses that meander through the region, alongside the gravel arroyos located northeast of Boise, especially those in proximity to historic Idaho City. The lure of unmined gold in the Boise Basin remains incredibly strong, making it a perennial hotspot for modern-day prospectors.
The Rye Flats Coin Cache
Further south in Boise County, near the Nevada state line at Rye Flats, another intriguing tale of lost wealth persists. Legend speaks of a shipment of newly minted gold coins, still meticulously wrapped in their original paper, being concealed within a sturdy metal box. This valuable cache, worth an impressive $40,000 at the time of its theft, was reputedly hidden inside an above-ground cave. The bandits who orchestrated this robbery never returned for their ill-gotten gains, leaving the significant hoard of gold coins waiting to be discovered by a lucky individual. This Idaho treasure is a testament to the unpredictable fortunes of the Old West.
Bonner County: Zak Stoneman’s Buried Fortune
The pristine wilderness of Bonner County holds the story of Zak Stoneman, a successful prospector whose fortunes took a turn in 1888. After a productive stint near Priest Lake, Stoneman was making his way to cash in his considerable gold findings when disaster struck. His pack mules, laden with three burro loads of gold, succumbed to poisoned weeds, dying on the spot. Forced to lighten his load, Stoneman buried his precious cargo in the area north of the Priest River, specifically three to four miles below Priest Lake. He intended to retrieve it later, continuing his journey on foot. However, upon his return, he tragically found himself unable to pinpoint the exact location of his buried riches. To this day, the legend states that Zak Stoneman’s substantial gold cache remains somewhere in this picturesque but challenging terrain, an elusive Idaho treasure for those who dare to seek it.
Cassia County: Range War Riches at Deep Creek
The 1890s saw Cassia County engulfed in a bitter and violent range war between rival cattlemen and sheepherders. As tensions escalated, the wealthier cattlemen enlisted the services of notorious hired gunslingers, including the infamous Jackson Lee Davis, better known as “Diamondfield Jack.” The conflict was brutal, resulting in the shooting of two sheepherders and Diamondfield Jack’s subsequent sentencing to hang for murder. He was later acquitted when James E. Bower confessed to the killings. Jack then moved to Nevada, where he eventually amassed a fortune in gold mining. Amidst this turbulent period, it is widely believed that both cattlemen and sheepherders, fearing for their assets during the escalating violence, cached their valuables around the critical water sources of Deep Creek and Shoshone Creek. These hidden caches represent a fascinating glimpse into the desperate measures taken during Idaho’s volatile frontier history, adding another layer to the lore of Idaho’s lost treasures.
Custer County: Isaac T. Swim’s Lost Quartz Vein
The rugged lands near the mouth of the Yankee Fork River in Custer County became the site of a tragic loss in the late summer of 1881. It was here that Isaac T. Swim, a seasoned prospector, unearthed a rich, gold-bearing quartz vein. Excited by his discovery, he swiftly journeyed to Challis, the Custer County seat, to officially file his claim. Returning in the Fall to collect samples, winter’s early onset forced him to postpone further exploration. The following June, Swim, accompanied by several other eager miners, set out to return to his promising quartz cropping. Their progress was halted by the Salmon River, which was dangerously high due to spring runoff. Despite Swim’s caution, the other miners were impatient. Swim, displaying his leadership, agreed to cross first and then return for the others. However, he never reappeared. His drowned horse was later found downstream, and Swim’s body was recovered later that summer. He had perished, taking the precise location of his rich quartz claim with him. Though his partners diligently searched, and one even found a claim marker across the river from the Yankee Fork’s mouth, the incredible gold vein was never rediscovered. A truly tantalizing prospect, this lost gold remains one of Idaho’s most sought-after phantom mines.
Idaho County: Robber’s Gulch Freight Wagon Gold
Southwest of White Bird, along the majestic Salmon River, lies a notorious locale aptly named Robber’s Gulch. More than a century ago, this remote canyon was the scene of a bold holdup involving a freight wagon carrying an immense fortune: approximately $75,000 in miners’ gold. The outlaws, after seizing their prize, hastily concealed the gold amidst the rocks of the gulch before attempting to escape into the forbidding Seven Devils area. Their luck, however, ran out. A relentless posse tracked them down in the mountains, resulting in a deadly confrontation where every single bandit was killed before any information about the hidden loot could be extracted. Consequently, the substantial gold cache was never recovered. To this day, the $75,000 in gold is believed to remain hidden somewhere in Robber’s Gulch, an alluring Idaho treasure waiting to be found by those who can decode its secrets.
Kootenai County: The Tragic Fate of Jack Breen’s Gold
November 1889 brought a significant discovery to Kootenai County when prospector Jack Breen located a promising gold deposit near Coeur D’Alene. Lacking the necessary funds to work his claim, Breen headed into Coeur D’Alene in search of a grubstake. He soon found partners in N. R. Palmeter and Jack Osier, though he kept the exact location of his find a secret, only revealing it was near Hayden Lake. To celebrate his impending fortune, Breen stopped at a local saloon. His bragging about the gold drew a crowd, with customers eagerly buying him drinks, hoping to coax the location out of him. Fearing Breen would unwittingly disclose his secret, his partners, Palmeter and Osier, persuaded the local marshal to jail him for “his own protection.” This decision proved to be a fatal miscalculation. Early the next morning, the jail caught fire, and before Breen could be released, he tragically succumbed to smoke inhalation. With his death, the precise whereabouts of his valuable gold claim became another lost chapter in the saga of Idaho’s hidden treasures. A somber tale that highlights the perils and desperation of the gold rush era.
Lewis & Clark Trail: The Lost Washington Season Medals
The historic journey of Lewis and Clark through Idaho in 1805 and 1806 brought with it not only documentation of new territories but also a unique form of treasure. As a gesture of peace and diplomacy, the expedition distributed approximately 55 “Washington Season” medals to various Native American Chiefs along their trail. These rare and highly valuable medals, crafted from solid silver and individually engraved, were produced in Birmingham, England, in July 1798. Of the 326 such medals received by the presidency, only a handful are accounted for today. It is widely speculated that many of these invaluable artifacts remain lost along the Lewis and Clark expedition route through Idaho, particularly in areas like Lewiston, Spalding, and Orofino. These medals represent not just monetary value, but also a profound historical connection to early American exploration, making them a unique category of Idaho treasure.
Shoshone County: Bank Robbery and Outlaw Caches
The Wallace-Kellogg Bank Robbery
Around the turn of the 20th century, the Wallace-Kellogg area in Shoshone County was the scene of a significant bank robbery. Bandits successfully made off with an estimated $80,000. Seeking refuge overnight, they purportedly buried their stolen loot somewhere within a four-mile stretch between Huettner and Post Falls. However, the law was close behind. The robbers were captured the following morning, but authorities failed to locate the buried cache. It is presumed the bandits were subsequently hanged, and the considerable sum of $80,000 has never been recovered, a testament to the enduring mystery of Idaho’s hidden wealth.
Butch Cassidy’s Idaho Cache
The notorious outlaw Butch Cassidy and his infamous gang are also linked to a lost treasure in Shoshone County. Legend has it that they buried a portion of their ill-gotten gains north of the old stage road, which once connected Spokane Falls, Washington, and Wallace, Idaho. The precise location of this cache is said to be along a creek, near a beaver dam. While Cassidy’s movements were extensive, the idea of his treasure lying undiscovered in the wilds of Idaho adds a thrilling dimension to the state’s outlaw lore, further enriching the tales of Idaho treasure.
Twin Falls County: The Lone Bandit’s Lost Strongbox
In 1888, a solitary outlaw targeted the Jarbidge-Idaho stagecoach near what is now the site of the Salmon Dam in Twin Falls County. The bandit, acting alone, managed to seize the stage’s strongbox. However, his escape was short-lived; a swift posse quickly overtook and killed him. Despite recovering the bandit’s body, the valuable gold strongbox was nowhere to be found. Many believe that the outlaw, in a desperate attempt to secure his loot, buried the strongbox on the east side of Brown’s Bench, a vast, flat mesa located approximately 15 miles west of Rogerson, Idaho. This lost strongbox, an example of a forgotten Idaho treasure, continues to pique the interest of those exploring the vast, unyielding landscapes of Twin Falls County.
