Logs of Test Holes and Wells

On the pages that follow are given the logs of 43 test holes and wells drilled in Logan County and adjoining areas (Pl. 2). Nine of the logs were supplied by drillers (drillers logs); the other 34 logs are of test holes and wells drilled by the State Geological Survey (sample logs). The test drilling by the Geological Survey was concentrated in upland areas to obtain detailed information on the thickness and character of the Ogallala formation. The geologic sections shown in Plates 3 and 4 are based mainly on data obtained from these logs.

Samples from test holes drilled by the State Geological Survey were collected every 10 feet or at each noticeable change in lithology. The samples were examined and logged in the field and later studied microscopically in the laboratory.
