I will present results of Spitzer IRAC and MIPS imaging of the star forming region associated with the NGC 2068/2071 reflection nebulae. The region contains moderately dense clusters of young stellar objects of a wide range of evolutionary states. Combining IRAC 3.6-8.0 micron and MIPS 24 and 70 micron photometry with ground-based optical and near-infrared measurements from the SDSS and 2MASS surveys, we have compiled spectral energy distributions for hundreds of sources. I will compare number statistics and spatial distributions for Class 0, I, and II objects from classifications based on the infrared SEDs. Stellar and accretion characteristics for a representative sample of these objects have been determined via low- and high-resolution optical spectroscopy obtained with Hectospec/chelle. Finally, I will show evidence for a significant population of evolved disks, some 5-10% of all disk sources, which suggests a wide variation in timescales for the onset of primordial disk evolution and dissipation in comparison to other regions with older ages.
