Whether or not the schools teach it, Phil has a point about mountain flying being much more than mountain landings.
Illusions, navigation, performance, enroute winds, and weather are all considerations that require additional attention in the mountains. I've flown a number of SARs in the Rockies and typically find crashes that occurred during the enroute phase, more so than the landing phase.
The important thing is to understand that the discussion here is not training. If you haven't been trained in mountain flying, don't use this discussion as your licence to kill (yourself). Take a course.
