If you put overhangs on opposite sides, the weight of the opposing overhang structure will provide for counterweight. I would still use tie down anchors since the consequences of your wall tipping or collapsing would be severe.
Jon, burning man is in the middle of a dried up lake bed in Nevada, google maps Black Rock City, Nevada, and that'll give you a pretty good idea. It's late august/early September of every year. Something about it starting the Monday after.. labor day I think?
Climbing Magazine posted a link to this (Craigslist ad for a climbing wall which was used at previous BM) on their Facebook this morning: sfbay.craigslist.org/eby/zi…
It might be sort of cool to recycle the one with a past.....
The flat thing protruding out the front on the ground will help stop this thing from tipping forward from it's own weight and the weight of a climber. Also the back flat spot could be a patio which would also help with the tipping. Hopefully this would make it so you wouldn't have to do any modifications to the ground. (concrete, anchors, etc)

Yup. we built one like that a few years ago and had huge 2 by 12's extended out for frame, and anchored back to framework on vertical wall. That or wires to hold back the upper portion weight. It can be done though.
