Logs of Wells and Test Holes

Listed in the following pages are the logs of 78 wells and test holes in Rice County, including 64 logs of test holes drilled by the State Geological Survey of Kansas and 14 logs of test holes of wells furnished by private drillers. The locations of the test holes are shown on Plate 2 and most of the wells are shown on Plate 1. The logs of test holes drilled by the Geological Survey are classed as sample logs, as a complete set of samples was collected from each test hole. The test hole numbers used in this report follow the same system as the well numbers. They give the locations of wells according to General Land Office surveys as described on page 10.
