W5 is an active region of star formation located at 2 kpc in the Perseus spiral arm within Cassiopeia. The western region of W5 (W5W) is defined by a large 1.5 degree diameter HII region rimmed by bright molecular clouds. The eastern component W5E is similarly characterized, extending about 1 degree in diameter. W5E is predominately ionized by a single O7 star, while W5W has several O-stars ionizing the region. We have surveyed W5 in the optical (Ha, [S II], and I filters) using the KPNO 4m wide-field MOSAIC camera, and at 1.1mm using Bolocam on the Caltech Sub-Millimeter Observatory on Mauna Kea. The region has also been surveyed with Spitzer using IRAC and MIPs. We will present a comparison between these various surveys with an emphasis on identifying and characterizing the Bolocam cores. Dynamics of the W5 region will be highlighted.
