We propose Spitzer/MIPS 24 micron observations in the HS1700+643 field to study the bolometric energy production from galaxies within and surrounding the most significant cluster-scale over-density at z>1.5, at a time when massive galaxies were forming most of their stars. This over-density is at z=2.300, placing the strong 7.7 micron feature observed in star-forming galaxies in the MIPS 24 micron filter, and therefore makes MIPS observations ideally suited for studying the star formation rates and energetics of galaxies as a function of environment. Stellar population modeling of broad-band UV to Spitzer/IRAC SEDs indicates significant differences in the ages and masses of galaxies within and outside of the proto-cluster. The proposed MIPS observations will allow us to determine if these differences extend to the bolometric energy output of galaxies in the proto-cluster and surrounding environment in a manner that is completely independent of the degeneracies of SED modeling and uncertainties in extinction. The extensive multi-wavelength data in the field containing the proto-cluster will allow for the unprecedented opportunity to compare MIPS-inferred bolometric SFRs with UV and Halpha estimates on a galaxy-by-galaxy basis to establish star formation relations for galaxies with a wide range in ages, stellar masses, and luminosities at z~2. Spitzer/MIPS observations of the HS1700+643 proto-cluster therefore offer the opportunity to understand star-formation and its environmental dependencies in a unique and well-studied laboratory at high redshift.
