Report describing the results of a program to test and evaluate the cross-country mobility of the Overland Train (a logistical cargo carrier) in a desert environment. This study used a system for terrain classification developed by the U.S Engineer Waterways Experiment Station as part of the tests made on various courses at the U.S. Army Yuma Proving Ground in Arizona.

"The purpose of this report is to present the results of an inspection performed at Laguna Army Airfield (LAAF), Yuma Proving Ground, Arizona, during December 1972. The inspection was limited to visual observations, and no tests were conducted on any of the pavement facilities. A layout of the airfield is shown in plate 1" (p. 1).

From abstract: During part of February and March 1953, reconnaissance examinations for radioactive material were made at 12 localities in the Yuma Air Force Base gunnery range in southern Yuma County, Ariz. The Yuma gunnery range, which is adjacent to the west edge of the Luke and Williams Air Force Bases gunnery range, is characterized by block faulted, elongate mountain ranges composed essentially of schist, gneiss, and granite of pre-Cambrian to Mesozoic age and separated by broad alluvial basins.

Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that will permit an accounting of ground-water return flows from each side of the Colorado River in the Yuma reach. The estimates of return flow can be used by water-management agencies in determining return-flow credits for the States of Arizona and California.

Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that permits an approximate accounting of ground-water return flow from each side of the Colorado River in Yuma reach. The method presented in this report was developed specifically for application in the Yuma area. The validity of the assumptions inherent in the method was evaluated on the basis of the local hydrologic system. The applicability of the method to other hydrologic systems is not addressed in this report.

Summary and conclusion: More than 4000 feet of Lower Miocene lake sediments were deposited upon a gneissic basement rock, at least locally. The sediments have been gently folded into broad anticlines and synclines and have been cut by high-angle faults with displacements on the order of 100 feet. Both basaltic (?) and acid andesitic lavas have intruded the sediments. A Pleistocene (?) conglomerate unconformably overlies all older exposed rocks. The lake sediments were considered to overlie the adjacent thick series of andesite flows (l). This was not established by a cursory examination. The sediments appeared to be in fault contact with the lavas although the relationship was always obscured by the younger conglomerate or alluvial cover. Since a dike of this acid andesitic composition was observed cutting the sediments, there is a possibility that the lake sediments are older than or contemporaneous with the thick extrusive andesite series.
