I am looking for any details about summiting Mt. Langley from Old or New Army Pass then down into Miter Basin to camp at Sky Blue lake. Then over Crabtree Pass to Discovery Pinnacle and then the best way to summit Mt. Hitchcock then down to Crabtree lakes #1. for camp#2. The biggest help I need is info on getting from Mt. Langley to Sky Blue lake, I was wondering if I had to backtrack back to Old Army Pass of is there a route down the western slope that is more direct. Any help would be appreciated.
