Is that red volcanic rock alongside the road to Fairmont?
Yep. Those red rocks are part of a large volcanic field that developed north and west of Butte about 50 million years ago. Big Butte (or “M” mountain) above Tech is part of this pile of volcanic rocks. Erosion has ensured that this area does not look like a volcano any more, but the rocks that are left give us some clues as to what it may have looked like.
