资源简介：
This data set is a polygon coverage created in ARC/INFO that
represents the generalized thickness of the Madison Limestone
and Englewood Formation, Black Hills, South Dakota. The
thickness of the Madison Limestone and Englewood Formation was
determined by substracting the elevation of the top of the
Deadwood Formation from the elevation of the top of the
Madison Limestone. The elevations for the tops of the
formations were determined from geologic logs for wells drilled
as of 1998. The thickness coverage contains polygons that have
single integer values representing a range of thickness.
