After summiting Whitney and spending a beautiful night at Upper Boy Scout Lake, left at approximately 9:30am up the dreaded scree slog to gain the Russell-Carillon saddle. Very little patches of snow here and there. Once gaining the saddle, climbed the East Ridge proper up and over the false east summit. As I approached the final summit, snow patches became more prevalent and very sketchy. The snow was soft, heavy and wet, and fearful entire slabs would slide off the north side with 1,200+ vertical drop, made for very mental and tiring climbing. Finally gained the final 60+ degree chute up to the summit. Post holed some and also caused many small slab avalanches which were nerve wracking. Quickly gained the summit and retreated before the sun warmed the slabs even more and cruised over to Carillon Summit. Another great day in the Sierra Nevadas.
