We recently completed a survey of Infrared Dark Clouds (IRDCs) with Spitzer to search for new outflows and to study the low-mass young stellar object (YSO) population associated with the IRDCs. The star formation activity of the sample ranges from candidate starless cores to IR−bright massive YSOs. The new, much deeper data will enable us to probe these clouds to lower mass limits to obtain a better census of YSOs in the regions, and to find outflows from deeply embedded objects using the 4.5 micron emission that were previously undetected. We will present some early results from this survey.
