Where can I find information about passes in the rockies to use when
flying over them?

Commonly used passes are indicated on the sectional charts.

Actually, for *real*(tm) mountain flying, a sectional is not good
enough. Look at any topographic map, and you'll easily find your way,
together with options for plan B and bail out. A scale of 1:200,000 or
better seems reasonable to prepare for and navigate during a flight
through unknown moutain terrain.

However, the correct answer to your question is: If you have to ask, you
shouldn't do it.
