A discussion is presented concerning the implications of, and questions raised by, the Cowboy underground detonations with chemical explosives. These experiments verified the correctness of the theory that explosions in a large cavity experience a decoupling effect, that is, the resulting seismic signals are muffled. The Cowboy tests left certain problems still to be solved e.g., the relationship between cavity volume and depth and the decoupling factor, and the possibility that chemical explosions produce significantly different curves from nuclear explosions under the test conditions.
