Great Cacapon - Hancock. July 17 Wednesday. Took the 6:30 train to Great Cacapon and crossed the river to the Western Maryland R.R. at Tonolow- gay [illegible]. Here above is seen the Crisfay sandstone dipping about 30° to the W., with a thickness of about 200 feet (the dip being 200 feet at 45°). These sandstones rest on a series of weathering red mud shale in which occur Physopleura, Lep- teaene chondralis, Strepho edata beds. This Newark land zone is at least 30 feet thick but this is a guess as the place is much covered by trees. Then follows blue limestone, then bedded sand and shaly slate containing an abundance of fossils. There are the Creemans beds as seen at the R.B.B. at Cumberland. The section here continues into the Marlins which is more modelled in li. The thickness seems to be as of Cumberland. Above the Physopleura beds appear to lie beds of thermal shale. The strike are dip East. The lower delina beds are first red, green and then a variegated series follows: blue, gray, red and light yellow that weather yellow. Around the top lying shales appear. Below the lying beds are above the Rhynchomella.
