Logs of Wells and Test Holes

The following are logs of 95 test holes drilled in Grant and Stanton counties. Sixty-nine of these test holes were drilled by the State and Federal Geological Surveys and are headed "Sample log of test hole in . . . "

These tests were logged by the authors during drilling and supplemented by studying the formation samples. Twenty-six of the test holes were drilled by commercial well drillers for individual land owners, and formation samples were collected; these are headed "Sample logs of test holes drilled by . . . " These 26 test holes were logged by the personnel of the Geological Survey from the formation samples and the descriptions may differ somewhat from that of the drillers.

In addition, 342 test holes drilled and logged by commercial well drillers are summarized in Table 19 and Table 20. An asterisk after the well number in Tables 19 and 20 indicates that a descriptive log is also included in this report, and an "e" after the altitude means that the altitude was estimated. Table 2 presents similar information from electrical and radioactivity logs.
