This report summarizes geologic and terrain information pertinent to the conduct of materiel testing at the U.S. Army Yuma Proving Ground. Surface features are described in two categories -- Bedrock Mountains and Alluvial Lowlands. Only the Alluvial Lowlands are extensively and continuously used in testing they, therefore, are treated in greater detail as differing in grain sizes of materials and relative degrees of surface dissection. The distribution of surficial materials, based on mapping at a scale of 162,500, is generalized at a scale of 1500,000 for this summary. The mapping program and related activities provide a basis for improvement of field environmental testing, particularly in relation to ground-vehicle mobility, surface transportability, and vulnerability to detection.
