The Lost Silver of Irish Canyon: Butch Cassidy’s Hidden Treasure in Colorado’s Outlaw Country

                                                                   Butch Cassidy

 In the far northwest corner of Moffat County, where Colorado leans into Utah and the land begins to feel more like outlaw country than anything mapped or measured, Irish Canyon cuts a narrow path through stone. In the late nineteenth century it was a place where men on the run could disappear without much effort. Butch Cassidy drifted through those cliffs more than once, and so did the rest of the Wild Bunch. Matt Warner and Isom Dart knew the canyon’s bends and shadows as well as any rancher knows his own pasture. They operated out of nearby Brown’s Park, a lonely valley along the old Outlaw Trail, a place where a rider could vanish for weeks and no lawman would bother to follow.

Irish Canyon offered exactly what men like Cassidy needed: isolation, rugged walls, and a dozen escape routes disguised as game trails. It was the kind of country where a rider could stash something valuable and trust the land to keep its mouth shut. According to frontier lore and the storytellers who keep these legends alive, the gang buried a fortune in silver coins somewhere in that canyon. The amount—thirty thousand dollars—was not out of character for Cassidy’s crew. They robbed banks, trains, and payroll couriers with a kind of reckless confidence, often riding away with sacks of gold and silver that would weigh down a lesser band of thieves.

Today, anyone heading toward the canyon follows the same general path: west from Maybell on the long stretch of US‑40, then north on Colorado 318, and finally onto the rough county road that threads into the gorge. The land looks untouched, as if the nineteenth century never quite left. Fremont petroglyphs still cling to the rock faces, and the formations rise in jagged shapes that make searching difficult. It is easy to imagine Cassidy himself riding through the narrow pass, glancing over his shoulder, deciding where to hide a heavy cache that needed to stay hidden.

Brown’s Park, just beyond the canyon, was a refuge for outlaws long before Cassidy arrived. Rustled cattle and horses were moved through the valley, and stories of buried loot were common enough that locals barely raised an eyebrow. Josie Bassett, one of Cassidy’s closest friends, lived there and often sheltered members of the Wild Bunch. Cassidy himself stayed for a time at Doc Parson’s cabin, a place where a man could rest, plan, and wait for trouble to cool. The remoteness of the region made it perfect for burying valuables. Lawmen rarely ventured into that maze of cliffs and sagebrush, and the terrain itself seemed designed to hide secrets.

Whether the Irish Canyon treasure is real or simply a tale that grew in the telling, no one has ever produced proof of its recovery. Still, the story fits the habits of the Wild Bunch. They were known to bury loot when the chase grew too hot, and they certainly handled enough stolen silver and gold to make such a cache plausible. They spent long stretches hiding in Brown’s Park and Irish Canyon, waiting for the world to forget their latest robbery.

The canyon keeps its silence. Landmarks from the nineteenth century have eroded or vanished, and outlaws were not known for leaving tidy maps behind. The place is large, rugged, and sparsely visited, and if multiple caches were ever buried, they may lie scattered across the canyon floor like forgotten chapters of a story no one can finish. Treasure hunters have combed the area for decades, but Irish Canyon remains stubborn, holding tight to whatever secrets Butch Cassidy may have left behind.
