Back in 2006, Dan and I hiked out to this known petroglyph site we’ve been wanting to check out for a while. It was a bit of a hike, but we were well rewarded.
We were very surprised to find historical inscriptions by cowboy and miner Bill Keys (of Joshua Tree fame) and others. By the 1895 date on the rock, Bill would have been just 15 years old when he carved his name on the rocks. This is a great site!
See the Wall Street Mill for some notes on Bill Keys.
