Military Geology of Guam, Mariana Islands. Part 1: Description of Terrain and Environment. Part 2: Engineering Aspects of Geology and Soils

This report on the Military Geology of Guam, Mariana Islands, has been prepared in cooperation with the U. S. Geological Survey, Department of the Interior, as part of the Pacific Geological Mapping Program of the Corps of Engineers, U. S. Army. The program is designed to collect and compile information on the military geology of areas of the Pacific, by field mapping and analyses of selected islands, and to publish the information in a form usable to the Armed Forces and the island civil administrations. The Descriptions of Terrain and Environment of Guam (Part I) includes basic data on geology, geography, soils, vegetation, and climate. Laboratory tests of rock and soil, and specific observations in the field furnish additional basic information, from which are evaluated the suitabilities for construction materials, road and airfield construction, and underground installations (Part II). Suitabilities of the terrain for amphibious and airborne operations and for cross-country movement are evaluated in a separate, classified volume (Part III). Water resources will be published as a Supplement. Prepared in cooperation with the United States Geological Survey.
