    The Montrose Placer Mining Company completed the hanging flume in Dolores Canyon in 1891. The flume operated for only a few years, but portions of it still hang from the canyon's sandstone walls.

    The dry climate has helped portions of the flume survive for more than 125 years. Most portions that remain are not completely intact. The brackets and floors are still there, but the sidewalls have fallen away.
