May 2-1913, Cumberland. Started into see Drills Creek section in the Juniata, Many of the red sandstones again have vertical tubes as we saw gesterday in the Dolina, here too some have vertical lining calicles concretions but they are rare. The vertical tubes are common however. The Anthrophychus larlani come in in Drills Creek (at time trip of the) at 30-feet beneath the shaly Tuscarora. The introduction of Clinton time was for then are no Clinton fossils. These Anthrophychus occur as usual on the under surface of the sandstone just above a shale bed from nothing to 4 inches thick. The Clinton fossils appear above the red dolomitized Tuscarora about 15 feet or so. See my former notes. The bend between the pink Juniata sandstones and above the white Tuscarora can be determined at the Rock where the spring comes out and where trump sleeps. This contact may be de- termined further towards Cumberland along the B & O track at land and return the end of the Brevoos residence stone wall. It is here over red white the Juniata and Tuscarora are always separated on the evidence of the petrographic color. This time break must occur here in spite of the similar decided petrographic character because the Tuscarora is typical of Medina and the Juniata cannot be other than the Ohio Richmondian. Elevation before yes even to transmutations earlier Richmondian and continued well into Lillieic time.
