Hiya, schmalz,
Have you looked at Clarence Kings' "Mountaineering in the Sierra Nevada" or pursued anything by Norman Clyde? Great stuff there. Also, look into early issues of the Sierra Club Bulletin for some great first hand accounts of early b'pking and mountaineering when only a handful of folks were out there doing it. More great history stuff in "Sierra Crossing: First Roads in California" by Thomas F. Howard, and "Sierra Nevada Lakes" by George Henry Hinkle. Yep, these mtns have awesome stories!
