Topography: Physiographic map of southern Guam
About this map:
This map shows physiographic provinces (major types of terrain) of southern Guam. It was created by digitizing the map provided by Tracey et al., 1964, Geology of Guam, U.S. Geological Survey (USGS), and slightly modifying it based on more recent USGS topographic maps.
