For the first time, [S II] and off-line continuum CCD emission-line imaging data have been obtained for the Rosette molecular cloud. At least 13 features showing excited gas have been detected. Three of the features appear to be due to external excitation from stars in the nearby open cluster NGC 2244 that are responsible for the ionizing flux that gives rise to the Rosette Nebula. Ten of the features appear to originate from driving sources within the Rosette molecular cloud itself, either as a result of the interaction of general winds from young stellar objects with the dense, prenatal material in the cloud, or from collimated outflows from young stellar objects (i.e., Herbig-Haro objects). Two of the features may be part of a parsec-scale Herbig-Haro flow.
