Well logs

Listed in the following pages are the logs of 60 wells and test holes in Grant, Haskell, and Stevens Counties, including 46 test holes drilled by the State and Federal Geological Surveys (1-46), 13 water wells (47-59), and one gas-test well (60). The locations of the test holes are shown on Plate 3 and most of the water wells are shown on Plate 2. Test holes 1, 2, 3, 4, 5, 23, 35, and 38 were drilled as a part of the investigation of the geology and groundwater resources of adjacent counties.
