Summary
A large stope in the Treadwell gold mine, Douglass Island, Alaska, 1908. A stope is an excavated underground cavity. The stopes at Treadwell were left mostly full of broken ore to provide a place for the miners to stand as they excavated upwards, then emptied when completed. Thick walls were left as pillars between stopes to support the rock overhead.
