I wonder how many of these stone and cement dams there are in JTree. And I wonder how many will still hold water after the rains. I've discovered a few on my own, but the intrepid 3-D photographer and rock charter - I'm talking about Murbachi - has found even more. Including one of the best, Surprise Tank.

There's a dirt road just north of Hemingway, it heads south to a number of small parking areas. Park in the third one you come to, it'll be on your left. You'll be looking up a rocky canyon and thinking, "why would anyone want to go up there." The answer? To see what you can find.

Rock climbers wander and crawl up and over these rocks for hours, just to reach a starting point for a dangerous climb. Me, I'm not that limber anymore, so I stick to hiking and scrambling.
