Logs of Test Holes and Wells

Listed on the following pages are logs of 190 test holes and wells in Wallace County and adjoining areas. Of these test holes, 70 are drilled, 31 are augered, and 4 are jetted, all by the State Geological Survey of Kansas. Also included are drillers logs of 51 irrigation wells, 32 seismograph shotholes, 1 domestic well, and 1 test hole. Logs designated "sample logs" describe test holes from which samples were collected. The logs are numbered according to the well-numbering system illustrated in Figure 2. Locations of wells and test holes are shown on Plate 1. Plate 2 illustrates the character of material penetrated by the test holes. Water-level measurements are stated in feet below land surface.
