In a follow-up of sorts to my last post, a visit to Yosemite resulted in me changing my college major to geology. Of course, after working in Yosemite for a few years, my interest in geology waned as my interest in bears grew. Yosemite can move your interests.

Anyway, for those who haven’t seen it, watch this nine-minute video about rockfalls in Yosemite (part of the Yosemite Nature Notes video podcast). It includes some amazing footage of the 2009 rockfall behind The Ahwahnee. (This footage is so fascinating, I’ve watched it probably a few dozen times—I guess my interest in geology hasn’t completely faded!)

If you liked that one, check out the other great episodes.
