Dates
Date Taken
1936
Summary
Form a panoramic view of upper parts of Tomahawk and Bear Creek Basins. The rugged forms of Babcock Peak and Mount Moss are due to erosion of monzonite. Several porphyry sills show clearly on Banded Mountain (right side of photo 35). Sedimentary rocks, all of them metamorphosed, belong to Upper Jurassic and Upper Cretaceous formations. The glaciated rock floors of the basin are exposed in a few places through the characteristically heavy accumulations of talus. View looking west from Diorite Peak with Tomahawk Basin on left. La Plata County, Colorado. Circa 1936. Plate 6-B, in U.S.Geological Survey Professional paper 219. 1949.
