Logs of Test Holes

The logs of 60 test holes in Mitchell County are given on the following pages. Of these, 29 are sample logs of test holes drilled by the State Geological Survey of Kansas, and 31 were drilled by the Bureau of Reclamation in conjunction with a study of the proposed Glen Elder dam. The logs of 12 test holes in a line across North Fork Solomon Valley are given by Leonard (1952) and the logs of 10 test holes near the Mitchell-Cloud county line are given by Bayne and Walters (1959). The test holes are numbered according to the system illustrated in Figure 2. Locations of test holes are shown on Plate 3. Plate 2 shows the character of material penetrated by test holes. Water-level measurements are stated in feet below land surface.
