This report by Willis T. Lee discusses the geology and groundwater in this agriculturally rich region of central California. This area was a significant water source for Los Angeles prior to the creation of the aqueduct system. Accompanying the 28 pp. report are five illustrative plates and a small untitled map covering the area from Mono Lake south to Owens Lake, surrounded by the Sierra Nevadas and White Mountains. Numerous rivers and creeks are depicted along with a proposed damn site south of Mono Lake. Folds into salmon colored paper wrappers.
Map is fine while text and plates are very good with light toning and isolated foxing. Library stamp on front cover, which is nearly detached.
