Regions of mid-infrared extinction against the Galactic background delineate high column gas having the potential to form stars. Studies of these infrared dark clouds (IRDCs) over the past decade have revealed high-mass cores and protostellar objects indicating that IRDCs trace early stages of Galactic cluster formation. Massive IRDCs that show minimal evidence for star formation activity are thus ideal subjects for characterizing the initial conditions of cluster formation. These high-resolution observations of massive, relatively quiescent IRDCs at sub-millimeter wavelengths offer an empirical point of reference for our understanding of cluster formation.
