Logs of Wells and Test Holes

Listed on the following pages are logs of 44 test holes drilled by the State Geological Survey of Kansas and of 2 irrigation wells. The locations of test holes are shown on Figure 7. Logs entitled "sample log" were those drilled by the State Geological Survey and for which samples were collected. A "drillers log" is a written log obtained from a driller or from some other source. The logs of irrigation wells 5-38-15cbb and 5-37-15bdd were obtained by K. Elias and were originally published in a report on the geology of Rawlins and Decatur counties (Elias, 1937, pp. 15, 16). Depth-to-water measurements obtained from test holes are included in the headings of the logs.
