The Jessie Mine and Mill
Dating back to the late 1880s, the Jessie Mine and Mill was once one of the largest gold, silver, and lead mining complexes in the Breckenridge area. Today, visitors can see the partially intact remains of the 1893 wooden stamp mill—the only one of its kind still standing in Summit County—along with several mine openings on the hillside above. The historic mill structure has been stabilized with a protective roof designed to match its original silhouette.
The story
In the late 1880s, miners carved into the hillside above Gold Run Gulch, eventually cutting seven distinct mine openings—including the Glenwood tunnel—into the rock. Blasted ore was sent down the mountain slope via a gravity-powered cable tramway to the valley floor, where an enormous wooden stamp mill erected in 1893 pounded the raw gold, silver, and lead ore into fine sand.
While most heavy industrial timber across Summit County collapsed under snow loads or got salvaged over the last century, the Jessie stamp mill held on as the single remaining wooden stamp mill in the area. Preservationists eventually pulled the leaning framework back near plumb using winches and steel cabling before capping it with a steel protective shelter roof shaped to match the mill's original 1890s silhouette.
What it's like
You reach the mill via the public Gold Run Trail, where the weathered timber skeleton sits set back across a small stream bed. A perimeter fence keeps you at a mandatory distance—the heavy frame is structurally fragile and the steep mine openings on the hillside above are strictly unsafe to enter. Read the interpretive signs near the trail, then pull out binoculars to spot the dark, collapsed shaft entrances dotting the slope behind the structure.
The move: Hike the scenic Gold Run Loop together to view the historic wooden stamp mill, read the interpretive signs, and spot the old mine openings on the hillside from a safe distance.
📍 Before you go The site is located along the public Gold Run Trail and managed by Breckenridge History, but the wooden mill structure and the steep mine openings on the hillside are structurally unstable and unsafe to enter.
