Abstract
The rock outcrops and glacial features exposed in Rock and Pipestone counties in southwestern Minnesota display unusual combinations of sedimentary features and occupy a strategic position for interpreting regional stratigraphic and tectonic events. Geologists have only recently begun to systematically study the area's features, and much of the past research has overlooked stratigraphic relationships and sedimentary structures, and instead emphasized the historic and economic aspects of the two counties' geologic deposits. Indeed the historic and economic aspects of the area's geologic features are extremely important, and to fully study the area and its geologic resources it is necessary to investigate the historic, economic, and environmental impact that the area's residents have had. This paper examines the stratigraphy and probable origins of the area's geologic deposits, and evaluates the area's resources with respect to their historic, economic, and environmental implications.
