Karst Map of Puerto Rico

This map is a digital update of The karst landforms of Puerto
Rico (Monroe, 1976). In this new version the karst areas on
the islands of Mona and Monito have been added from Briggs and Seiders (1972). This map
will serve as the basis for the Puerto Rico portion of a new
national karst map currently being compiled by the U.S.
Geological Survey. In addition, this product serves as a
standalone, citable source of digital karst data for Puerto Rico.
Nearly 25 percent of the United States is underlain by karst terrain, and a
large part of this area is undergoing urban and industrial
development. Accurate delineations of karstic rocks are needed
at the national, state, and local scales. These data will lead to a
better understanding of subsidence hazards, groundwater
contamination potential, and cave resources, and will serve as a
guide to topical research about these rocks.
