Project Cowboy was an experiment undertaken to validate a seimic decoupling theory. The theory postulates that the seismic effects of any explosive energy release can be reduced by detonation in a cavity (decoupled) instead of in a packed and tamped (coupled) cavity. Project Cowboy consisted of detonating a series of chemical high explosives emplaced in a deep ({similar_to}800 ft.) underground spherical cavity and of comparing the seismic effects of these explosions with the effects of the detonation of identical charges packed into tamped drill holes. This report describes the project management activities in 1959 and 1960, the engineering planning, expenditures, and excavation progress at the salt deposit site in Louisiana. (LCL)
