Well Logs

Logs describing the materials encountered in test drilling in the Neosho valley are listed in the following pages. All of the test holes were drilled in January, 1942, by the portable hydraulic-rotary drilling machine owned and operated by the State and Federal Geological Surveys. Field descriptions of the samples were made by James Cooper, sampler for the drilling crew. These descriptions were amplified by the author after examining the samples microscopically in the laboratory.
