A program of experimental blasting carried out in Alaska during winter, 1970, is described, and results are given. Results of earlier studies on shaped charge penetration and crater formation by single concentrated charges are reviewed and summarized. Blasting procedures for excavation of trenches in deeply frozen soils are considered. (Author)
