You start in a low angled crack and move up jugs in two parallel crack systems until you commit to the right crack. Solid protection. Watch out where you're smearing some of the slab is loose. The route is short and pretty chossy. Fun beginning trad lead. I don't think it has seen very many ascents.

If your looking at the Great Burrito from the nature trail, Scamp is located on the far left part of the wall. Walk toward the wall and negotiate boulders (can get tricky) till you get to the farthest left crack on the formation and you're there. Descend the 4th class corner on climbers left.
