Homestake II Project; Eagle County, Colorado, USA
Tasks Performed: Consultant responsible for preparing feasibility and cost studies for 17 kilometers of water supply tunnels. He directed and supervised the work of 15 professional geologists. The field work was carried out at a high altitude between 4,000 and 4,500 meters under extreme weather conditions in one of Colorado’s most rugged mountain ranges. He performed detailed geological field investigations to determine support and lining requirements for the tunnels. The geological investigations consisted of aerial photography interpretation followed by onsite mapping of faults and shear zones, and detailed fracture mapping. All geological data from surface mapping was statistically evaluated to predict tunneling conditions. This was performed by making use of various rock classification systems.
Duration: 1982-1983 (10 months)
Description: The Homestake II Project is located on the Western Slope of the Colorado Rocky Mountains in the rugged Mt. Holy Cross Wilderness. It was part of an ongoing study to develop the water resources of the Eagle River Basin for both in-basin use and transmountain water diversion to communities located on the Eastern Slope of the Colorado Rocky Mountains.
