Digital Map Of Base of Aquifer for High Plains Aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Description
This data set consists of digital base of aquifer elevation
contours for the High Plains aquifer in the central United
States. The High Plains aquifer extends from south of 32
degrees to almost 44 degrees north latitude and from 96 degrees
30 minutes to almost 104 degrees west longitude. The outcrop
area covers 174,000 square miles and is present in Colorado,
Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and
Wyoming.
This digital data set was created by digitizing the base of
aquifer elevation contours from a 1:1,000,000 base map created
by the U.S. Geological Survey High Plains RASA project
(Gutentag, E.D., Heimes, F.J., Krothe, N.C., Luckey, R.R., and
Weeks, J.B., 1984, Geohydrology of the High Plains aquifer in
parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South
Dakota, Texas, and Wyoming: U.S. Geological Survey Professional
Paper 1400-B, 63 p.) The data should not be used at scales
larger than 1:1,000,000.
