EXCAVATIONS IN FROZEN GROUND. IGLOO FOXHOLES
Tests were conducted near Houghton, Mich., in December 1954 to determine the feasibility of producing man-sized cavities beneath the frozen ground layer. Charges from 0.1-10 lb of low-velocity explosives (Coalite 7S and Gelodyn 1) were fired at depths from 10.5-48 in. in ground frozen to a depth of...
