Logs of Test Holes
Given on the following pages are logs of 41 drilled test holes, 9 drilled observation wells, 80 jetted observation wells, and 1 oil well. The logs are arranged by township from north to south and by range from east to west. Within a township they are arranged by section number. An explanation of the numbering system is given on page 13 and a diagram is shown in Figure 2, Two test holes were drilled by the State Geological Survey in 1944, 39 test holes and 9 observation wells were drilled in 1949, and 80 observation wells were jetted in 1950. Samples of the materials penetrated in the test holes and observation wells were examined in the field by geologists who supervised the drilling and prepared the logs. The samples subsequently were studied microscopically by D, W, Berry and A. R. Leonard. General locations of the test holes are shown on Plates 2 and 3. Logs of test holes 2, 5, 6, 7, 39, 40, 41, 44, and of Hays wells 3, 15, and 20 on cross section C-G of Plate 3 are given by Latta (1948).
