Old Bones Pass

by Phil Martz (

I would recommend a change in classification for Old Bones Pass from class 2 to class 3, or to class 2-3. On a two week exploration through the Ritter Range and the Lyell-Maclure area, I crossed Old Bones Pass from north to south. The descent of the first 100 feet on the south side of the pass was difficult and should probably be done by removing packs and roping them down over a couple of difficult sections.

I have compiled a waypoint file (Sierra passes.tpg) for use with TOPO! maps, of about 100% of off-trail High Sierra Passes. The file is at Download and open in TOPO! for locations of passes. I am continuing to update this file with more passes and notes on passes. Any comments please send email to me at
