This is the basal member of the Cataract formation as we saw yesterday but at Cataract it is 12 feet thick. Over the sandstone the exposure is not clearly shown but sufficiently once to make out a zone of green shales with thin bedded limestones that on some horizons are refulete with dolomite. By around the thickness is 64 feet, at the top, the shale is brick red and has some dolomite. These red bits are not that finally 2 to 3 feet and are sandy and sort of limestone.
