What drives the correlations between galaxy properties and environment? How
do they evolve with time? We combine ACS imaging with ground-based optical
spectroscopy for 3 cluster at z~0.8 to investigate the evolution of the
correlation of galaxy properties such as color, morphology, and star
formation rates, and environment. The clusters, CL0152-1357, CL1604+4304,
and CL1604+4321 were chosen to cover a range of X-ray luminosity, and thus
mass. Here we present preliminary results for CL0152-1357. Of the sample of
102 cluster members, we find 33 star-forming galaxies and 2 AGN. We have
morphological information for 24 of the star-forming galaxies. Five of these
are compact early-type galaxies, and seven are red cluster sequence spiral
galaxies. The remaining 12 are blue spiral and irregular galaxies.
