Brief report:
A warm up climb for Mt. Shasta's Casaval Ridge the next day. There were 10 foot walls of snow at the parking lot. Lake Helen was still with thin ice. I left the parking lot (8500') at 11:00am. En route (at about 9700'), I climbed the prominent rocks to the climber's right of the south side short couolir. From Bob Burd's website, he mentiones this to be class 3 rock, 200 ft high. I must have gotten off route because the route I took (about 300 yards to the right of the couloir) felt like solid class 4, even a few low 5th moves. It took me some time to climb this section. Once out of it, the summit was not far. I reached the summit at 12:30pm. It was very windy up there and I didn't stay long. I got back to the parking lot at 1:40pm. Changed the sweaty clothes for dry clothes and drove out there by 2:00pm, heading to Mt. Shasta.
