In the 1890s, gold drew up to 3,000 people to Duncan, Colorado; by 1900, most buildings had been dismantled after US marshals moved to remove them

Imagine walking through the highlands of a Colorado mountain pass in 1874, stumbling across a few pieces of gold-bearing rocks in an area of creek bed, and watching a scattered prospecting claim grow over the next two decades into a town with a hotel, bakery, newspaper, and even a bathhouse. Unfortunately, the town grew and then declined just as quickly, as the federal government sent in US marshals to dismantle Duncan piece by piece.

Today Duncan is barely a note on a hiking trail within Rio Grande National Park, something not many Americans will have heard of. According to historical accounts and the U.S. Forest Service, which now manages the site, Duncan was a short-lived boomtown in Colorado. It peaked during the gold rush with up to 3,000 people moving in, and the town had disappeared by 1901.

Prospecting for gold


John Duncan was not looking for history when he crossed Medano Pass into the San Luis Valley in 1874. He was simply looking for floating gold ore. As per the detailed local history published by Colorado Central Magazine, Duncan found a deposit of floating gold ore at the mouth of Pole Creek. Although he never found any wealth, he knew that selling land would make him money. He sold lots to prospectors for $75 each.

By the time it was officially established in 1892, Duncan had grown into a town with a hotel, restaurant, grocery and general store, clothing store, livery, bakery, bathhouse, and its own newspaper, the Duncan Eagle. Stamp mills crushed ore brought down from the mines up Pole Creek, and families built cabins to settle into the remote valley. For a time, Duncan looked set to become a lasting fixture in Colorado.

A dispute over land that was never really theirs

Duncan’s residents believed they had legitimately purchased their land from the State of Colorado. In reality, the town sat inside the boundaries of the Luis Maria Baca Grant No. 4, a vast 19th-century land grant whose exact borders had not yet been formally surveyed. When rancher George Adams bought the grant in 1899 and had it surveyed, the homeowners of Duncan were found to be squatters on his land, according to a Colorado Public Radio account of the dispute. A legal battle followed, and the courts ultimately ruled in favor of the Baca Grant’s owner.

When US marshals came for the cabins

In 1900, U.S. marshals were sent to the valley to enforce the court’s ruling. Contrary to the violent image suggested by some retellings, the process itself was a compensated, orderly removal: homeowners were paid $125 per structure and given the option to buy their own homes back for $10, provided they moved the buildings off the grant entirely.

Separately, tensions in the valley ran high, and one night a small cluster of cabins at nearby Dead Man’s Creek was destroyed by an explosion: reportedly three cabins, with debris thrown hundreds of feet. No one was ever identified as responsible, and it was never established that marshals had any role in it. Almost every other building in Duncan was either torn down or hauled away. The one exception was John Duncan’s original cabin, built in 1874; the town’s oldest structure predated Duncan’s own founding as an official town by nearly two decades. That cabin still stands today, having been preserved first as ranch-hand housing and later restored by the Forest Service; it can now be rented out for an overnight stay.

America’s forgotten ghost town

Many of the families moved a mile or so away from Duncan and created a new town called Liberty. It struggled with a school and stagecoach route; however, it also disappeared, per the Colorado Encyclopedia. Neither town ever got close to the wealth they promised. They serve as a warning that during the gold rush in America, it was easy for everyday people to lose their claim to the land if they didn’t have the best paperwork.
