Well Logs

Listed in the following pages are the logs of 144 wells and test holes in Pawnee and Edwards Counties, including 133 test holes drilled by the State Geological Survey of Kansas. The numbers of the logs correspond to the numbers used in the diagrammatic cross section (Pl. 3).

Logs entitled "sample log" are those for which the well cuttings were collected and studied. A "driller's log" is a written log obtained from a driller or from some other source.
