Overlying surficial deposits and absent areas for the Minnekahta Limestone, Black Hills area, South Dakota.

Data describing where the Minnekahta Limestone is directly overlain by
surficial deposits and areas where the formation is absent were used in the
production of structure-contour maps for the top of the Minnekahta Limestone
(mnktscon). This data set was created as part of the Black Hills Hydrology
Study (BHHS). The BHHS is a long-term investigation that was initiated in 1990
as a cooperative effort between the U.S. Geological Survey (USGS), the South
Dakota Department of Environment and Natural Resources (DENR), and the West
Dakota Water Development District. West Dakota represents various local and
county cooperators. The purpose of the study is to assess the quantity,
quality, and distribution of surface and ground water in the Black Hills area
of western South Dakota (Driscoll, 1992). The study area includes parts of
Butte, Custer, Fall River, Lawrence, Meade, and Pennington counties in South
Dakota.

This data set describes areas where the Minnekahta Limestone is directly
overlain by surficial deposits, as well as those areas where the Minnekahta
Limestone is absent in the Black Hills area, South Dakota.
