The Mammoth “earthquake fault” and related features in Mono County, California

Abstract

In undertaking this work it was our intention to investigate the well-known "Earthquake Fault" situated about two miles northwest of the town of Mammoth in Mono County, California. In working in the surrounding region we found, however, that this is only a part of an extensive system of similar features. The locations of those which have been found thus far are shown on the map (fig. 1), which is reproduced from U. S. Geological Survey topographical maps, Mount Lyell and Mount Morrison quadrangles. We consider that the southern and eastern limits of the features shown are real, whereas in the northern and western directions they represent only the extent of our investigations to date.
