back at the lower workings of the Champion Mine, standing on the second wall, looking at a funny, corrugated outcrop. If I look at this outcrop with a tilted head, I might imagine a sideways, not-quite-upside-down Nevada with corrugations of the Basin and Range forming large-ish mountain ranges (or I might imagine caterpillars crawling).
|Closeup of the corrugated outcrop.|
|Thin rinds of dumortierite on schistose, Triassic rhyolite.|
|Fibrous to bladed dumortierite up close.|
|Dumortierite in irregular veins cutting the Rochester Rhyolite.|
|Veins and a vein breccia.|
|Nice vein of fibrous dumortierite.|
