We present combined CARMA and FCRAO 12CO(1-0), 13CO(1-0), and C18O(1-0) emission line maps of the Serpens Core as well as 2.7 mm continuum images from CARMA alone. The maps sample spatial scales from 5" up to 10' (2000 AU to >1 pc). The Serpens Core is a dynamic, active star-forming region. Several remarkable features are revealed in the combined maps including outflows, shells, remnant cavities from outflows, and filaments. The continuum maps are remarkably sparse despite the presence of extended, dense gas as traced by the C18O emission. We are in the process of cataloging the energy injecting sources. In later analysis we will determine the power spectra of velocity and density fluctuations in the field to compare to models of star formation as well as determine the influence of these energetic source on the surrounding medium. The CARMA maps are part of a three-region survey of large (75-150 pointing) mosaics that includes Perseus B1 and NGC 1333.
