Hi Andy-- Yes you're in the ball park at 5.11-(pin scars help) .Just around the corner from this (up canyon) is another route called "Scuzznies Slot"(5.10 b/c?),both climbs led without bolts.----Cheers,JN
This nice looking crack (5.11-?) is located on a separate wall about 10 minutes from the main wall. To locate it, walk up the main trail until just past a foot bridge. Follow a trail to your left towards the cascading creek and then cut right along the base to find this wall. I didn't have time to climb this route, but apparently there are no fixed anchors on top. Looks short but sweet!
