Abstract: Laboratory tests were conducted on rock core samples received from five holes from Natrona and Fremont Counties, Wyoming (Warren II Study Area). Results were used to determine the quality and uniformity of the rock to depths of 200 feet below ground surface. The rock core was petrographically identified as predominantly granite and biotite gneiss. Several specimens of amphibolite gneiss and biotite schist were also identified. The wide area represented by the fivedrill holes and the complex nature of the material preclude assessment of the area on a hole-to-hole basis. The overall appearance of the area is one of a complex rock mass with quite variable physical properties. However, based on the limited data available; the area offers possibilities as a competent hard rock medium if poor quality schist can be avoided. Except for the schist, poorer- quality rock is predominantly in the upper elevations, but one may expect to remove up to 70 feet of material in some areas before competent rock is reached. A more extensive investigation will be required to identify the most promising hard rock areas.
