Abstract:

Laboratory tests were conducted on rock core samples received from core holes drilled in the balaltic flows of the Mountain Home, Idaho, and Fairchild, Washington, areas. The results were used to determine the quality and uniformity of the rock to depths of 200 feet below ground surface. Specific gravity, porosity, and compressive strength tests indicated the rock from both areas to be highly variable in physical properties. The outstanding variables were the degree of vesicularity for the Mountain Home rock and the vesicularity and a pattern of incipient fracturing for the Fairchild rock. The denser rock from the Fairchild area appeared to be inherently stronger and more rigid. Author
