Johnny Lang first saw Lost Horse Valley in 1890, when he and his father dove a herd of cattle into the area and set up camp. One morning, they awoke to find their horses gone. Johnny tracked them to the McHaney brothers’ (local cattle rustlers) camp. The McHaneys informed Johnny the horses weren’t there and he’d better leave the area. Some time later, Johnny met up with a man named “Dutch” Frank. Now Dutch had a rich mining claim, but was afraid to work it because of the McHaney boys. So he sold the claim to Johnny and his father for $1,000 and they named it the Lost Horse mine.
