Introduction
During 1950, a series of 43 test wells 30 feet deep were drilled by the United States Corps of Engineers along the western edge of the Everglades from the Tamiami Canal northward to the Caloosahatchee River. The cores obtained from the wells afford geologic data along a line from the lower Everglades of Dade County, where both the geology and water resources have been investigated, to the Caloosahatchee River area, where the surface geology has been studied.
This report has been prepared chiefly to record and interpret the information obtained from the test wells. It is one of a series prepared on ground-water investigations by the United States Geological Survey, in cooperation with the Florida Geological Survey. When ground-water data become available they will be correlated with the geology of this report and will be presented in a later report on the Glades-Hendry Counties area. A few generalized inferences concerning ground water are made.
The investigation was under the general supervision of A. N. Sayre, Chief, Ground Water Branch, U. S. Geological Survey, Washington, D. C., and Herman Gunter, Director, Florida Geological Survey, and under the direct supervision of Nevin D. Hoy, District Geologist, U. S. Geological Survey, Miami, Fla.
