Abstract : Project Pre-GONDOLA III Phase III, the connection of a row crater to a reservoir, was executed on 6 October 1969 and was the culmination of several years of cratering experiments in saturated clay shale near Fort Peck, Montana. This experiment used a total of 70 tons of an aluminized ammonium nitrate blasting agent in a row of five charges to remove a barrier between an existing row crater and the Fort Peck Reservoir. The excavation resulting produced by the detonation had a volume of about 63,000 cubic yards. The blasting agent appears to have a cratering effectiveness approximately 1.6 times that of TNT.
