We present preliminary analysis of 1-8~\mum photometry of the young stellar clusters GGD~12-15 and IRAS~20050+2720 from IRAC on Spitzer, FLAMINGOS on MMT, and 2MASS. Each cluster has on the order of 100 members in a high density asymmetric configuration as well as significant outflow activity. However, their far-infrared luminosities differ by more than an order of magnitude. Combined ground-based near-infrared and IRAC colors are used to identify stars with circumstellar disks. Class I (protostars) and Class II (stars with disks) objects are classified via IRAC 3-8~\mum color analysis. The spatial distributions of all young stars with infrared excess emission detected are compared with published gas and dust distributions for these regions.

Based on observations from the Spitzer Space Telescope (operated by JPL/Caltech, NASA Contract 1407) with support provided through NASA Contract 960541 from JPL/Caltech.
