Clamshell Cave hosts a variety of moderate climbs, including some enjoyable moderate cracks. Most of the lines are either trad lines or require trad gear. It is easily possible to toprope most of the lines by scrambling around the right side of the crag. Most routes end at bolted anchors. The hangers on the anchors seem to come and go, a definite nuisance since options for gear at the top of the crag aren't great. Be prepared to use the anchor on a neighboring route.
Park 5.4 miles up Icicle creek canyon and look for a trail on the north side of the road. A well travelled and sometimes braided trail reaches the base of the crag in 10-15 minutes.

Nice, clean crack, only wish it was 4x the length. Crux is right off the deck with a tricky entrance move. Overall, the crack is hand-sized and takes feet well, although there are adequate face features for hands and feet as well. Note, old guidebook called this 5.7, but the 2003 version up-rated it to 5.8. ...[more] Browse More Classics in WA
