Description:

Abstract:

This dataset shows the approximate locations of selected caves on Guam. It includes selected vadose caves (created by dissolution above the water table), selected phreatic caves (created by dissolution under saturated conditions), natural arches, coastal collapses, and sea caves. The indicated locations of caves are approximate. Caves were originally identified in the field and their approximate locations were subsequently noted on topographic maps. Due to most cave entrances being in remote locations under thick canopy or bases of tall cliffs, GPS units were not utilized at the time of fieldwork. The points labeled on maps were later digitized into a series of GIS shapefiles, which were compiled, projected where necessary, and compared to create the master-file. The information contained within this file is a subset cleared for public distribution. It excludes features that were deemed sensitive.

Purpose: To inventory karst features on Guam.

Supplemental_Information: This is the master file with over 180 cave features.

Access_Constraints:

Access to the master data set restricted due to the sensitivity of the natural features. Please contact the originator for detailed information.

Process_Description:

Several GIS shapefiles, provided by the originator, needed a projection file and/or were reprojected where necessary and compared to create this master-file. The attribute table was 'cleaned' by removing duplicated fields. Quality control was provided by the originator.
