I think Harvey is correct. The peak above the notation "Consultation Lake"(which is actually Crabtree Pass) is Mt. McAdie with Mt. Marsh just to the north. Between McAdie and Irvine is Arc Pass which has Consultation Lake to its north. The plateau labeled "Upper Boy Scout Lake" is the plateau to the north of Crabtree Lakes with Discovery Pinnacle on its NW end and the Whitney trail just over the north edge.
Nice Photo.
