Deposits from the caldera-forming eruption 9,400 years ago, about 5 kilometers outside the eastern caldera wall.  AVO scientist Dr. Jim Gardner stands near the base of ~6.5 meters of pumice fall, capped by ~2.5 m of densely welded pyroclastic flow material.  Additional pyroclastic flow material above is obscured by slope wash.  In the foreground is the top of the welded portion of pyroclastic flow deposit.
