Climbing leaders need a course in basic geology, see West Ridge Cuttroat report.
Mass wasting, the geological term, should not include Mountaineers.
When I used to guide and teach climbing professionally, I would ask my clients and students to consider how all those rocks in the scree and talus slopes got there. Later as national park ranger, it became obvious that ignorance of basic geology was widespread, as evidenced by the body bags included with our gear.

Basic knowledge of the geological process of "mass wasting,"
specifically rock fall, could make climbs such as Cutthroat Peak up near Washington Pass safer.
