OFR10-06, Cuttings Summary for the Minnesota Department of Natural Resources South-Central Drilling Program

Abstract

This report summarizes the glacial and bedrock geology for 15 drill holes completed by the Minnesota Department of Natural Resources (DNR) during 2008 and 2009. Cuttings from each drill hole were collected at the drill site by DNR staff, processed in the Minnesota Geological Survey (MGS) soil lab, examined and interpreted by MGS staff, and archived in the MGS cuttings collection. Geophysical logging was completed at each site by the MGS. The geologic interpretations for both the glacial and bedrock cuttings should be considered preliminary. This is due to the fact that field work for the MGS south-central atlas project is still in progress (recently collected field samples and drill core are still being processed and interpreted). Findings from this data may require reevaluation of some interpretations made in this summary. The following notes are provided to assist in understanding the formation descriptions (listed stratigraphically from youngest to oldest) in the glacial portion of the summary.
