Abstract We present the preliminary results of a study of the very highest energy jets observed by CDF and their substructure. Jets are reconstructed using the Midpoint algorithm with cone sizes of 0.4 and 0.7 and corrected with the standard jet energy corrections. We select events with at least one jet with transverse momentum > 400 GeV/c in a sample of 5.95 fb-1, and study the angular structure of the energy flow within the jet, as well as the overall jet mass. We have performed various studies to validate and calibrate these jet data, as well as understand their possible sources. We measure the jet mass and two measures of substructure, angularity and planar flow.
