We present the analysis of seven band (1.2 to 8 micron) ground andspace-based imaging of the NGC 7129 young stellar cluster from FLAMINGOS onMMT, 2MASS, and the Infrared Array Camera (IRAC) on the Spitzer SpaceTelescope. An analysis of the H-[4.5] vs. J-H colors reveals 84 objects withcircumstellar disks. Of these, 42 are located within the cluster core, a 0.5 pc(100'') radius region of enhanced stellar surface density. From a luminosityand extinction limited sample of the stars within the cluster core boundary wehave determined that 54% +/- 14% have circumstellar disks. Finally, we reportthe detection of several resolved outflows in the IRAC 4.5 micron mosaic.
