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 clusters 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.
