We present the latest results of the High-Redshift Large Scale Structure Survey, which is a systematic search for structure on scales greater than 10 Mpc around known clusters of galaxies at redshifts of z > 0.5. For this survey, we are using the Large Format Camera on the Palomar 5-m telescope to obtain optical/near-infrared imaging of a 24 arcmin region around previously studied high-redshift clusters. Colors are used to identify likely companion clusters and to map the distribution of supercluster members across the field. This technique has already been used to identify successfully the Cl 1604 supercluster at z = 0.9, a large scale structure containing at least seven member clusters. We present the most recent candidate superclusters to be detected through this program. The goal of this survey is to identify and examine a large sample of superclusters during an active period in their history. With such a sample, we can begin to constrain large scale cluster dynamics and determine the effect of the larger environment on galaxy evolution.
