I was just in Boston Basin to climb Sahale Peak on 6/30/19 and it appears that the gully to Sharkfin is mixed and melting quickly. As a result, I am only allowing basic graduates prior to the 2019 class and intermediate students on this climb. 

In your leader permission request, please include a recent climbing resume noting experience on steep snow and ice as well as exposed fourth class scrambling.

We will ascend to the routes via Cascade Pass and camping at Sahale Glacier camp. Expect Monday to be very long if we are able to get all three peaks in.
