A geologic reconnaissance of the Inyo Range and the eastern slope of the southern Sierra Nevada, California by Adolph Knopf with a section on the stratigraphy of the Inyo Range by Edwin Kirk. Washington: Government Printing Office, 1918. 29x23 cm (large octavo), pp. [1-2] 3-130, 21 plates, 8 diagrams, 2 folded maps (in pocket on inside rear cover), original gray wrappers printed in black. First edition. At head of title: "Department of the Interior / Franklin K. Lane, Secretary / United States Geologic Survey / George Otis Smith, Director / Professional Paper 110." This report, based on field work performed in 1912 and 1913, considers the geography and geology of the Owens Valley and portions of the Inyo Range to the east and the Sierra Nevada to the west between which it lies. Special attention was given to the problems connected with the geologic history of the Sierra Nevada and with the structural relation of that range to the lower arid country to the east. The area studied by Knopf overlapped that examined by A. C. Lawson, whose pioneer work provided the foundation for modern geologic knowledge of the southern Sierra Nevada (see Andrew C. Lawson, The Geomorphogeny of the Upper Kern Basin. [Berkeley: The University Press, February 1904]). Knopf's observations indicated that glaciers played a larger role in shaping the canyons, provided evidence for two epochs of Quaternary glaciation, and identified the remnants of the "summit plateau" as projections of a composite intrusive mass which resisted the erosion of the "sub-summit plateau." Wrappers tanned, small chip from lower edge of rear wrapper, rear wrapper detached as is often the case, a very good copy of a now scarce report. (#166219).
