The Lost Cement Mine
In 1857, two miners wandering lost in the Eastern Sierra discovered a vein of rich, red volcanic cement-like rock that was packed with pure gold. They chipped off a few pounds of the rock, showing it to others when they made it to town. In 1860, one of the miners died, but left a map to the site to a friend. Famous figures, including Mark Twain and the legendary guide Gid Whiteman, searched extensively for the "red ledge" near the headwaters of the Owens River. Some believe it lies buried under a volcanic ash layer from more recent geological activity.
Field Research Notes
Concentrate your efforts in the Devils Postpile / Mammoth Scenic Loop area. Look for outcrops of reddish volcanic tuff or cement-like conglomerates.
