Felsic gneiss
Gneiss, schist & quartzite. Paleoproterozoic, about 2,500 to 1,600 million years old. 41 crags on this site have their map point on it.
What the map says
Light-colored gneiss characterized by a predominance of quartz and feldspar. Biotite commonly forms less than 10 percent of the rock. Interlayered biotite-gneiss, hornblende gneiss, or amphibolite are locally abundant. Locally contains abundant sillimanite (20 to 30 percent of the rock).
1:100,000 sheet: Trimble and others, 2003, U.S. Geological Survey Geologic Investigations Series I-856-H (41 crags). A contact line at that scale is about 100 m wide on the ground.
