    dct:description """This digital data set consists of saturated thickness 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 106
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 saturated
thickness contours from a 1:1,000,000-scale base map created by
the U.S. Geological Survey High Plains Regional Aquifer-System
Analysis (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
are not intended for use at scales larger than 1:1,000,000.""" ;
