The history of Aspen’s mining had an interesting end where the last mining was near the location where it began. Many early mines began with a shaft. That was the shortest distance to the ore.

Aspen’s longest tunnels, and those with longevity, had several things in common. Most of their length was driven after 1900, all of them were designed to tap ore at the lowest possible tunnel level that could exit to the outside and they drained water from workings above.
The longest tunnel on the face of Aspen Mountain was the Durant. It exited near the Aspen Alps not far from the eastern edge of Little Nell. It was best known, until a cave-in blocked it almost at its entrance, as the tunnel that took you to the underground waterfall, a favorite of Aspen teenagers for decades.
