Well Logs

On the pages that follow are given the logs of test holes drilled by the State Geological Survey in Republic and Cloud counties. Eighty-four test holes were drilled in Republic County and 29 in Cloud County. The logs were prepared from field studies of the well cuttings by James B. Cooper and O. S. Fent supplemented by laboratory studies by me. Also given are the logs of four test holes drilled by the Bureau of Reclamation in the Republican River Valley, two test holes drilled by the Layne-Western Company near Concordia, and seven test holes drilled by the Air-Made Well Company near Concordia.
