About this map:
This map shows the extent of Holocene beach deposits along the coast of southern Guam. The geospatial data were extracted from the detailed geologic map of Guam, produced by Guam by Siegrist, H.G. and Reagan, M. (2008) as a reinterpretation and revision of the Geologic Map of Guam by Tracey et al. (1964).
