Pilot hole "x" was drilled to test the formations through which the ventilation shaft for the proposed federal Bureau of Mines demonstration oil shale mine would be drilled. The geologic formations encountered in this hole are discussed. Correlation of the geologic horizons encountered in this hole with those encountered in nearby drill holes was accomplished by using geophysical logs. Data on the geophysical interpretations are provided. The anticipated geotechnical characteristics of the geologic units encountered in pilot hole "x" are described.
