Abstract: This presentation, with the aid of slides, is about methods of blasting large quantities of glacial ice and snow. The project illustrated here involved blasting sections of a hanging glacier and a full year's snow pack threatening a work site. It was carried out by Mountain Consultants Inc. of Whistler, B.C. under contract to Omni Resources Inc. of Vancouver, B.C. in the period of September 1978 to October 1979. The reason for this project was the discovery of a molybdenum ore body in the north Coast Kountains (Boundary Ranges) near the Alaska/BC border. The exact location was 40 km east of the Juneau Icefields above the abandoned mining town of Tulsequah, B.C. The exploration company attempted to complete a feasibility study to bring the mining property into production. Also discussed are methods of controlling ice falls by helicopter, blasting lake ice and the Yokullhaup phenomena.
