Geologic Mapping in the Black Hills at 1:24,000 scale

Project Description

The need for 1:24,000 scale geologic maps has become crucial in parts of the Black Hills of South Dakota, however, geologic map coverage at this scale ranges from good quality published maps to areas that have little or no mapping. The Geological Survey Program is producing geologic maps in areas of the Black Hills where these maps are needed, in cooperation with the South Dakota School of Mines and Technology, the West Dakota Water Development District, and the U.S. Geological Survey EDMAP Program, and the National Park Service.

Why are maps like this needed?
