Fri. Oct. 16. Load down the river trail as far as the creek about 1/2 miles away. On way back went down on beach where we made our first finding (it was fairly low tide) to have a look at the geology & see if I could find any fossils. weathering product of recent time. bedded, but scarcely consolidated my fine sandstone high tidal mark low tidal marks equally soft sandstones with some shales where beds have slight dip to west. As I read the picture there is a slight break in sedimentation where the beds lying horizontally come in contact with the dipping beds. Both seem to be late Pleistocene or Recent in age, non-fossiliferous, & to contain a good deal of cross-bedding. Whether Lacustrine, marine or aestuarine in origin I have not found out. Suspect marine however. The hills & ditch here [illegible] them are merely the products of differential weathering of horizontal strata of soft shale & sandstone. Picked up the valves, still hinged together, if a fresh water clam. Also what may be a fossil seed (but fine) set in the sandstone left on the beach. (P.S. Not a foal) The topmost layer of the diagram follows the contours of the surface. It is mixed reddish-brown sand clay, almost exactly similar to the subsoil I secured at Lake Davienville. Another interesting bit smoked out of tree this a.m. See cat. # 3005. Sat. Oct. 17. Put on a drive to get the handicart if this place. Its tracks appear in muddy low places close to the river. Setting bs steel traps for it! Also went out for snelling again. Unsuccessful this time treated at least a dozen trees. Brien & Rand picked up some Emballonura bates, apparently the same as at Black Rim, Palmer Junction & L. Davienville. This form I shot a caseaway. He was just walking about in the woods.
