Jul 25, 2019 (Therese Pettigrew) - White pegmatites intruding graded wackes. The pegmatites contain muscovite, a greenish mica, tourmaline, and are cross-cut by late-stage vuggy amethystine quartz veins. At this location, samples were collected from the pegmatite that contain thumb-sized clots of molybdenum. The southernmost outcrop along this section had large (cm-scale) books of green mica.
