We just returned from Yosemite National Park where we stayd for a week. Rock climbing, rafting and sun. We climbed the Snake Dike on south west face of the Half Dome. 5 hours in the sun. The route wasnt too hard except for the major runouts. We used 60 meter rope and on some pitches there was only one pro to use. Meaning allmost 30 meters of unprotected climbing.
