Sallie Barber Mine

Perched high in the Golden Horseshoe mining district near Breckenridge, the Sallie Barber Mine is a historic zinc mine established in 1880. Today, visitors can hike or bike to the site to find a well-preserved wooden headframe, ore bins, and a steel-grated shaft. The surrounding area offers expansive views of French Gulch and the remnants of Summit County's rich mining era.

The story

While thousands of prospectors swarmed Summit County chasing gold pan dollars in 1880, a handful of miners punched a shaft high into the ridge above French Gulch hunting something far less glamorous: zinc. The Sallie Barber Mine spent decades pulling heavy zinc ore and lead out of the mountain while gold operations grabbed local headlines. When federal wartime orders later shut down gold mines as nonessential to the war effort, zinc producers like Sallie Barber kept their machinery cranking to meet industrial demand.

What remains at the summit today isn't just a pile of rotting timbers. In summer 2022, preservation crews reinforced the historic wooden ore bin and stabilized the iconic headframe before timber decay could drop it down the slope. Right underneath that headframe sits the original shaft opening, now capped with a heavy steel safety grate that lets you stare directly down into the dark workings below.

It is the quiet, scattered industrial debris that makes the site eerie: rusted steam boilers half-buried in dirt, iron cable fittings, and sprawling rock tailings where plant life still struggles to grow. You didn't hear it from us, but dropping a tiny pebble through the steel grid and listening for the faint clink off the shaft walls gives you an immediate, chilling sense of how deep into the mountain those miners actually went.

What it's like

The walk up is a steady, easy-going 2.8-mile round-trip along a wide, unshaded dirt service road that climbs roughly 390 feet through conifer forest. It's a shared-use corridor, so expect to pass casual family hikers, snowshoers in winter, and mountain bikers who frequently descend from higher Bald Mountain trails. The summit opens up into a high-altitude industrial cemetery with panoramic views across French Gulch. You can walk right up to the safety perimeter fence to inspect the timberwork and peer through the steel mesh grate over the shaft. Hit the trail early on a weekday morning if you want to inspect the ruins in silence without dodging bike traffic.

The move: Hike or snowshoe the scenic 2.8-mile round-trip Sallie Barber Trail together, stopping at the summit to photograph the historic wooden headframe and enjoy panoramic mountain views.

📍 Before you go The mine site is located along a public trail managed for historic preservation, but the actual mine shaft is securely grated and the remaining wooden structures are structurally unstable and fenced off for safety.

  • Santiago MineDrive east over the pass to compare Breckenridge's timber shaft with a remarkably intact 1930s gold flotation mill sitting above 12,000 feet.
  • 7:30 MineHead into Silver Plume to explore another late-19th-century boomtown operation, named for its miners' unusually late 7:30 AM shift start.
