"Lower Black Point Below the red sandy magnesian lime-stones are brick-red oolite, shales with zones of sandstone that become more coarse and conglomeratic (see Williams statements of Thursday). In places these brick red shales are sun-cracked. Collected some fossils here only a sandstone and Parks spirithrea (the once known species). The red beds against the hummian show clearly the effects of contact as the org. li. are here more and more sandy and even conglomeratic as one proceeds toward the Hummian. All the strata seen today are decidedly domed due to the irregular bottom although some of the doming is due to differential settling and subsequent earth movements. When the sea came in there were east and west trending hummian ridges of considerable heights, varying from 10-500 feet or more, even still sticks out on north Clarke Island partly as much as 200 above the chazze (up to 700 today) and still other ridges to the north were then probably nearer height to subsequent elevation some of which certainly remained in special times. Left Little Current at 8.15 P.M. In Manitou - Araming, arrived Lake at about 11 P.M.
