Logs of Wells and Test Holes

Listed on the following pages are the logs of 57 wells and test holes in Wichita, Greeley, and adjacent counties. Included are: the logs of 26 test holes in Wichita County and 24 test holes in Greeley County drilled by the State Geological Survey during the course of the investigation; 1 test hole drilled during the study of the geology and ground-water resources of Scott County; 1 test hole drilled during the study of the geology and ground-water resources of Hamilton and Kearny counties; 2 irrigation wells in Wichita County; 1 of the municipal wells at Leoti; and 2 deep test wells to the Dakota formation. The locations of the test holes drilled by the State Geological Survey of Kansas are shown in Figure 12. The samples from the test holes were collected and studied in the field by Prescott, who supervised the drilling and prepared the logs of the holes.

Logs entitled "sample logs" were of wells drilled by the State Geological Survey for which samples were collected.
