Logs of Test Holes and Wells

On the following pages are listed the logs of 59 wells and test holes in Finney and Gray counties, one test hole (1) in Scott County, one test hole (12) in Kearny County, and two test holes (28 and 29) in Ford County. Logs 1 to 29 are of test holes drilled by the State and Federal Geological Surveys (fig. 7). Logs 30 to 60 include logs of test holes drilled by other agencies and well drillers, logs of water wells (pls. 3 and 4), and partial logs of oil tests. Lithologic terms used in the driller's logs have been retained. The term "gyp" has been used by many drillers to describe the harder lime-cemented beds in the Ogallala formation and undifferentiated Pleistocene beds. "Quicksand" and "pack sand" have been used by some drillers to describe loose fine sand, and "sand rock" has been used to describe sandstone. Many of the softer unconsolidated beds of the Ogallala formation and Pleistocene deposits have been logged as clay, but in those wells from which cuttings are available for study most of the so-called clay was found to be silt. Because of lack of detail in the driller's logs of oil tests, no attempt was made to correlate these logs (58-60).
