The three day Muir route climbers are back down safely this afternoon. Yesterday the team spent the morning working on snow school and rope-travel skills, and then proceeded up to Cathedral Gap on the way to the high camp at Ingraham Flats. After digging a snow pit to assess the snow layers and potential avalanche hazard, the guides decided the risk was too great given the amount of new snow on the upper mountain and descended back to Muir for the second night.
