Logs of Test Holes

Given on the following pages are sample logs of 16 test holes and drillers' logs of 4 wells. Additional logs of wells and test holes are retained in the files of the U.S. and State Geological Survey offices, Lawrence, Kans., and may be examined there. The drillers' logs were obtained from drillers' records and are essentially unchanged. The locations of the wells and test holes are shown on plate 1.
