start [3062] Sep.17-1909. Friday. Left at 8.30 for Richmond. Arrived at Richmond at 10.20, At 10.35 started on for for Elkhorn Falls, 4 miles to the south-east Got there a little before noon. The bridge over the Creek crosses the Clinton and the falls are less than 7 or 8 feet down stream. Took several pictures and of the Clinton contact. The Richmond (Cummings bed 16 f 1.41 A.) [printed, sandy] is very even bedded and on other refaces the Crinoidal Clinton limestone with pockets of fossil at 2 to 3 feet above the base. The clay because the clinks has clay down bed between is very thin here. The contact is plainly seen because of the very different lithology on the fauna. See Cummings report p.657. This afternoon saw slipped down Clinton. 1/2 mile down the creek from the mill at Elkhorn Falls maybe seen the Clinton-Rick- mond contact. Drawn as drawn in the opposite side and of the place show 3 crinoids. The top of the Richmond is very even bedded of a greenish calcareous thin bedded material that in the weather will completely break down. Has many byzra, Hebutella sinuata,
