Description: Special Report
Summary: Blast effects of 1-6 sticks (205 gm. Each) of 40% gelatin and charges of 0.5-2 lb. of TNT placed at depths of 0-102 in. were studied near Alta, Utah during February-March 1956 in snow ranging from 110-120 in. deep. Disturbance of the snow by the blasts was determined by the diam. of the outermost concentric cracks, the diam. of the crater, and the depth of the crater. With constant charge, the diam. of the cracks or crater increased with increasing charge depth until a maximum was reached, beyond which the value decreased rapidly to zero. With constant charge depth, the crack diam. increased with increasing charge. Ram profiles showed an inhomogeneous age hardening in the crater. Temperature measurements indicated snow warming in a vertical profile line in the crater’s center. Problems and proposals for a future test program are summarized.
