Just look on a map (or Google Earth), find nearby peaks, look them up on SummitPost, and find the 3rd class routes. Secor's book is a great resource, too. Some classy ones, though: N ridge on Tyndall (the rib is boring--do the ridge), W face or SW ridge (latter sandbagged) on Williamson.
Thank you, guys. I appreciate your advice. Shortlisted these ones:
Williamson via West Face
Tyndall North Rib or Ridge
Now I need to pick 1-2 from the list. Convenient approach to the trail and relative proximity to the Whitney area would be a plus - I don't want to waste a lot of time on driving ) Looks like the first two (Middle Pal and Williamson) are the most likable by you, guys. Any suggestions?
