Start inside a three-sided chimney (the telephone booth) with a handcrack in the back. The chimney ends and the crack gets wide. Continue to the top and rappel off a tree.
Location
This is on the left-hand side of the Yosemite Crack Zone. The route is just past a prominent pillar leaning up against the wall.
I found the bottom part of this climb to be fun, but the top was pretty miserable (wide on less than stellar rock). We ended up having to hike/climb up and around to the spike anchors, because I wasn't comfortable rapping on the slings we found.
