The watersheds at higher elevations are underlain by highly deformed cyclically-, graded-bedded, non-calcareous, non-sulfidic meta-pelites and quartzites. Lower in the watersheds, particularly in East Bear, calc-silicate gneiss underlies a significant area. These rocks have been metamorphosed to greenschist facies, and locally higher grade, in contact with non-foliated granite dikes and sills. The metasedimentary rocks are
