The northern Adel Mountains of central Montana provide several excellent examples of laccoliths tangentially attached to feeder dikes that are members of radial swarms. The radial distribution of the dikes appears to be controlled by stresses imposed by the load of an overlying central volcano. Model experiments using colored gelatin to simulate magma injected into a tank of uncolored gelatin duplicate the geometry of the radial dikes and field relations between feeder dikes and laccoliths as observed in the field.
