About this map:

This map shows the caves in northern Guam whose location and vertical extent is such that they intersect the water table and, as a result, contain permanent pools of fresh or brackish water. The geospatial data used in this map are derived from a wider coverage of caves of Guam, based on Taboroši, D. (2002), Karst features of Guam [MSc thesis], University of Guam, Mangilao, 324 pp. The indicated locations of caves are approximate.
