Abstract
The bedrock exposed in the Low Wassie Quadrangle, Missouri, comprises
Late Cambrian and Early Ordovician aged dolomite, sandstone, and chert.
The sedimentary rocks are nearly flat-lying except where they are adjacent
to faults. The carbonates are karstified and the area contains numerous
sinkholes, springs, caves, and losing-streams.
This map is one of several being produced under the U.S. Geological Survey
National Cooperative Geologic Mapping Program to provide geologic data
applicable to land-use problems in the Ozarks of south-central Missouri.
Ongoing and potential industrial and agricultural development in the Ozarks
region has presented issues of ground-water quality in karst areas. A
National Park in this region (Ozark National Scenic Riverways, Missouri
) is concerned about the effects of activities in areas outside of their
stewardship on the water resources that define the heart of this Park.
This task applies geologic mapping and karst investigations to address
issues surrounding competing land use in south-central Missouri. This
task keeps geologists from the USGS associated with the park and allows
the Parks to utilize USGS expertise and aid the NPS on how to effectively
use geologic maps for Park management. For more information see: http://geology.er.usgs.gov/eespteam/Karst/.
