Logs of Wells and Test Holes

Listed on the following pages are logs of 35 selected wells and test holes. Logs of an additional 56 wells and test holes used in the preparation of this report are retained in the files of the U.S. and State Geological Surveys, Lawrence, Kans., and may be consulted there.

The logs are numbered according to the well-numbering system illustrated on figure 2. Location of wells and test holes are shown on plate 1. The character of the material drilled is illustrated on plate 2. Logs designated "sample log" describe test holes which were drilled by the State Geological Survey of Kansas and from which samples were collected. Water-level measurements are given in feet below land surface.
