The Lee Creek Mine of Texasgulf, Inc. is a major phosphate-mining operation located in the central North Carolina Coastal Plain. Early mining investigations indicated that 1) the phosphate ore could be economically recovered only by dry strip-mining methods, and 2) that artesian ground waters in the formation (Castle Hayne Limestone) underlying the ore would have to be controlled.
This paper relates the application of ground-water hydrology in depressurizing the Castle Hayne aquifer to facilitate dry strip mining at depths of 130 feet below mean sea level. The information presented here was excerpted from Hird (1971).

Southeastern United States: Third Annual Midyear Meeting, 1986, Raleigh, North Carolina
Southeastern United States–Guidebook is comprised of twelve field trips that were organized for the Third Annual Midyear Meeting held in Raleigh, North Carolina in 1986. The spectrum of geologic time represented in the Upper Precambrian, Lower Paleozoic, Mesozoic, Cenozoic and the very Recent. The geologic provinces are the Valley and Ridge, Blue Ridge Mountains, Piedmont, and the Coastal Plain. Besides North Carolina, trips include Virginia, South Carolina and West Virginia.
