The town of Mammoth Lakes is located within an ancient caldera, and signs of volcanic activity are everywhere - cinder cones, lava flows, hot springs, tuff, pumice, ryolite, and constant earthquake activity. On Minaret Road there's even a good-sized fissure in the earth. Geologists argue as to whether it's a fault or just a fissure - but either way, it's interesting to look at.
I thought this old snag looked pretty cool!
