To probe the earliest eras of cluster formation, we need to find clusters with a variety of morphological states and masses across redshift space. Here, we present results from the Clusters Occupied by Bent Radio AGN (COBRA) Survey. The COBRA survey includes 646 bent, double-lobed radio sources selected from the VLA FIRST Survey, infrared observations from Spitzer, and optical observations from the Discovery Channel Telescope. The COBRA survey spans the redshift range 0.5 < z < 3.0 and includes objects with a wide range of masses and dynamical states. The bent radio morphology results from interactions between the AGN host galaxy and the surrounding intracluster medium; the relative motion results in ram pressure acting on the lobes, bending them. Using our IR and optical data, we measure galaxy excesses, locate red sequence galaxies, and determine photometric redshifts. We find that at least 30% of our high-z the bent radio sources are found in clusters or protoclusters. Additionally, we measure galaxy surface densities to trace out the large-scale cluster morphologies.
