Geno, I worked on a road job north of Shasta out in the 'humps and bumps' . One of the engineers told me that rock that makes that wild landscape is Andesite, and he thought the flow from the north crater was so large and sudden, it engulfed water, tree, and vegetation, which exploded as huge steam boils shoving up those peaks. That ground is just riddled with lava tubes, a few of which contain ice caves only a couple hundred yards from a hot cave emitting clouds of steam on a cold morning.
You are just south of a hot fault, watch the horses buddy, watch the horses, they can feel it coming.
