3 AM start at Top spur. Scramble with a rope, crampons, and ice axe up Cathedral Ridge. Early snow helped reduce loose rock. Summited then back at the glacier in 3.5 hours. No water. Had a stove and didn't use it. Bad idea. 85-90F in the trees for the 4 mile deproach below McNeil Hut. Back at the car by dark. Total climb car to car 17hrs. ~7K ascent
