Logs of Test Holes

On the following pages are given the logs of 28 test holes drilled in Clay County (Pl. 2). The holes were drilled chiefly in areas of thick alluvial deposits, but several were drilled to determine the character, thickness, and water-bearing properties of the Dakota Formation. One test hole was drilled through the gypsum deposits in the northeastern part of the county. The geologic cross sections shown in Plate 3 are based principally on data obtained from test-hole logs. Many holes were drilled with a power auger to determine the depth to water level or as a guide in preparing the geologic map. Logs of these auger holes are not given, as most of them were very shallow. The test holes were drilled by the State Geological Survey. Samples were collected and studied in the field and later examined microscopically in the laboratory.
