DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Polygon regions of the upper confining unit of the Floridan aquifer system

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains areas underlain by the upper confining unit. Geologic maps and thickness from test borings and wells were used to define its extent. Isolated areas of upper confining unit material may lie outside this boundary.
