Castaway has an interesting mix of single pitch trad and sport routes on a relatively small, steep outcropping. The rock is gneiss (typical of this area), so be prepared to confront lichenous, sometimes insubstantial rock in places. Most of the routes are on the colorful north face, receive little sun and offer an escape from a hot day. Two recently installed sets of top anchors allow quick raps from all routes. "What's My Line" (10b), a challenging trad lead up a series of thin interconnected cracks, will keep you in suspense. "Atmospheric Testing" (10+ sport) will definitely expose you to the rarified air.
