There are a lot of passes missing from the list, outside of the Whitney area, and there are quite a few missing from the Whitney area, but I think you are thinking of the Whitney Pass for one.
Also missing are Crabtree Pass, Rockwell Pass, Army Pass, New Army Pass, Siberian Pass and Forester Pass.
Uh....all of those are listed, save Army Pass, Whitney Pass. But I was thinking of one in the more immediate Whitney area.
Hmmm...incomplete list makes this less fun......I'll give you credit for Whitney Pass. There is another.
