Logs

On the following pages are listed the logs of 80 wells and test holes in Ford County [in township order]. Logs 1-21 are of test holes drilled by the State and Federal Geological Surveys (fig. 2). Logs 22-80 include logs of test holes drilled by other agencies, logs of water wells (pl. 2), and partial logs of oil tests.

Most of the logs of water wells were obtained from drillers' written records but a few were supplied from memory by well owners. Lithologic terms used in the drillers' logs have been retained. The terms "gyp," "gyp rock," "magnesia," or "magnesia rock" have been used by some drillers in describing the harder cemented beds in the Ogallala formation. Many of the softer unconsolidated beds of the Ogallala 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.
