Surficial Geologic Map of the Ivanpah 30’ x 60’ Quadrangle, San Bernardino County, California, and Clark County, Nevada

Introduction

This map was prepared as part of a suite of surficial geologic maps covering the northern Mojave Desert to investigate neotectonic features and map soils of relevance for ecological properties. The map covers an area of the eastern Mojave Desert that includes the Cinder Cones, Cima Dome, Ivanpah Valley, and Lanfair Valley and includes major mountain chains of the Providence, New York, and Ivanpah Mountains, all within the Mojave National Preserve. Surficial geology includes expansive pediments, broad valley-bottom sediment tracts, and dune fields of the Devils Playground. Two Quaternary fault zones are identified, as well as several others that probably are Quaternary.
