Abstract : 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 1:62,500, is generalized at a scale of 1:500,000 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.
