Google just free-wared the keyhole software (the company they bought to make google maps). It is a lot like the google maps satelite images but you can actually pan, rotate and tilt. Mountains (and some cities) are rendered in 3D! It is amazing, you can fly up the valley from Lone Pine to Whitney! Once it is done streaming all the data down (you really need broadband), it labels all the peaks and features. Clyde Meadow, UBSL, Thor Peak, Russell, Irvine, Langley, etc... Aparently that little lake we called girl scout lake is called Frog Pond. I'm looking at new and old Army passes right now. It also display the altitude of the feature under your cursor!
If you use the modifier keys like shift, you can fly through, pan annd rotate.
You need to run it on Windows for now and it needs a fast machine with a butt load of RAM but it is a real kick.

I'm not sure how useful this would be to people who have never been up the peak but it might give you a small idea of what to expect.
