Spitzer-IRAC has obtained four-color images of the nebulosity and point source distribution at the center of the massive CO outflow in DR21. The nebula is characterized by emission from warm and hot dust, and from shocked gas. The IRAC images penetrate deeply enough to identify numerous ridges, filaments, and small nebulous objects. The point sources are spread throughout the nebula. IRAC images firmly identify the luminous object "IRS1" as being embedded in a thick, obscuring dust lane about 20" away from the nominal IRAS position for this object, but coincident with an HII region discovered at 6 cm. Nearby, and less extinguished, is a cluster of luminous point sources which may also play an important role in the outflow(s). We have in addition obtained new, deep, Ks images which show counterparts to every IRAC point source, and which contribute to the photometric analyses of the cluster. We will present these results, and discuss the implications for the outflow phenomenology.
