Logs of Wells and Test Holes

The logs of 32 wells and test holes are given on the following pages. There are logs of 13 auger holes and 8 hydraulic-rotary test holes, all put down by the State Geological Survey of Kansas. A log is given for 1 well drilled by the city of Wichita. Drillers' logs are given for 1 well and 9 test holes drilled by private contractors. The samples from test holes drilled by the State Geological Survey and a part of those drilled by private contractors and the city of Wichita were examined and logged in the field. The logs that are designated "sample logs" were prepared after microscopic examination of the samples in the laboratory and comparison with the field log. The letter (T) following an altitude of land surface figure indicates that the altitude of the test hole was determined from a topographic map.

Logs of 369 additional wells and test holes in Sedgwick County are available on request from the State Geological Survey of Kansas as Special Distribution Publication 22. The locations of these logs are shown on Plate 1.
