A fun zig-zag crack with a fitting name. The Swain guide calls this a 5.5, but I'd say it's a bit more technical than that. Climb the crack left, then turn right at the crux (where the crack heads right). Either climb the face on the left or the wide crack on the right, then head up to the tree.
Location
All the way at the end of the Near Trapps. Look for the 5.6 A3 roof on the right with fixed gear and walk downhill to the left, turn right and find the route on the face.
