Project Pre-Gondola I was a series of chemical explosive, single-charge cratering experiments in weak, wet clay shale conducted by the U.S. Army Engineer Nuclear Cratering Group as a part of the Joint Atomic Energy Commission-Corps of Engineers nuclear excavation research program. The four 20-ton nominal charges were detonated during the period 25 October to 4 November 1966, near the edge of Fort Peck Reservoir approximately 18 miles south of Glasgow, Montana. Motions of the ground surface were measured by high-speed photography of surface ground zero. Author
