After bagging Muir and Whitney, I descended Whitney's North Face to the low point between Whitney and Russell. Then I cruised up the Class 3 South Face of Russell. Most of the climb was on Class 2 loose talus and sand. There was a fun (albeit short) section of Class 3 rock near the top.
Some time I need to go climb some of the more demanding routes on Russell. The Mithal Dihedral looks awesome.
