The lower 100 feet of the Brandon exposed is a dark brown dolomite, much crushed and broken and dips steeply to the south. These layers have an abundance of marine fossils. Above are strata of clay sandstone, thin reddish of a light olive color. There is also in some beds a fine crystalline crylomite. Sorry mistake. The dip of these beds are clayey and become almost horizontal. Near the south east corner of this ore which is about 200 yards wide the beds are again sharply bent up on arc, exposing the fossiliferous layers of the Brandon which now against the Chazy.
