Cougar (Independence) Stamp Mill

If you’re interested in mining or historical ruins, this is a must-see. But don't wait too long. The only structure still standing, the giant ore bin that once fed the stamp mill, looks like it's barely holding together. From the area in front, where the old concrete foundations once held machinery, you’ll see five or six huge wooden beams that lean hard in one direction, clearly under severe stress. Another heavy winter of snow or a big storm, and the bin might collapse altogether.

One remarkable detail can be seen in the timbers: nearly every large square beam still carries marks from hand-shaping tools. These grooves, cut more than a century ago, remain etched into the wood, a tangible link to the immense labor of the miners and builders who worked here.

Climb the hill behind the ruins, and you’ll eventually reach a flat plateau. This was likely where ore was hauled in by road (or cable system) from the mine uphill. On some maps, you’ll see adits or tunnels labeled “Independence Mine,” “Cougar-Independence Group,” or “Independence Group.” The flat zone is now heavily overgrown, even 50 feet of forward progress can be tough going.
