Abstract

A Gish-Rooney type earth resistivity apparatus was used to obtain depth to bedrock at 110 instrument locations in north-central Des Moines County, Iowa. The variable depth method was employed in an area where some bore hole information was already available. The features on the resultant bedrock configuration map are more clearly defined than those on a map produced from bore hole data only. The resultant map is considered to be more reliable. The reliability of the method depends on the geologic conditions and the amount of data available prior to the study.
