Abstract:
    We investigate the influence of environment on brightest cluster
    galaxy (BCG) evolution using a sample of 63 clusters at 0.3<=z<=0.9
    drawn primarily from the Las Campanas Distant Cluster Survey and
    follow-up V, I, and K' photometry. Our data originate from a variety
    of telescopes and instruments. The cluster sample and observations
    used here stem from deep optical and infrared follow-up imaging of a
    small subset of the full catalog that was obtained to aid in the
    classification of candidates and to develop photometric redshift
    indicators.
