The Ivanpah quadrangle covers about 3,900 square miles in the northeastern part of the Mojave Desert of southeastern California and southern Nevada. It includes many mountain ranges 6,000 to 7,000 feet in altitude, and a single peak, Potosi Mountain, attains 8,504 feet. The ranges are separated by broad alluvial filled valleys and the lowest area, near the southwest corner, is about 1,000 feet above sea level.
