DENR releases new state geologic map South Dakotans can get a better idea of the state's geology now that two new map products are available through the Department of Environment and Natural Resources.
Titles of the new maps are Geologic map of South Dakota and Bedrock geologic map showing configuration of the bedrock surface in South Dakota east of the Missouri River.
"These maps are the first of their types in more than 50 years for South Dakota and represent a significant step in providing much-needed geologic information," said DENR Secretary Steve Pirner. "They reflect the knowledge gained through more than 40 years of drilling by DENR's Geological Survey Program."
The Geologic map of South Dakota shows the surface geology of the entire state. It is the culmination of more than 15 years of research, mapping, map compilation, and digitization.
The Bedrock geologic map showing configuration of the bedrock surface in South Dakota east of the Missouri River shows the bedrock geology that exists just underneath the glacial sediments.
It is a product of the DENR's oil and gas initiative wherein information relevant to the exploration and development of oil and gas is being made more readily available.
"Now that the maps are in a digital format, they can easily be updated and moved to the Internet," said Derric Iles, state geologist. "This will allow the latest information we compile on the geology in South Dakota to be available to the public."
The maps are available for free viewing or download from the Geological Survey's Web site (http://www. sdgs.usd.edu) and will be available in digital format for use by industry, consultants, and researchers. Paper copies of the maps can be ordered as well.
