mrs found a good coal washin. Oysten also occur here. The oust sandstone S.E.
is not prolificum folliwd by a thin which bear numerous small fossils along Baculites and cephalites. About 1/3 mile more S E, there is a very prominent outcrop, which I will examine tomorrow.
Rock Creek shows clearly how a long plane is produced. One side of the creek thus is low bluff the one on the northern side most precipitous with the creek meandering through its alluvial bottom. On the higher terraces no alluvion can be detected. At different times this stream has cut down its bed to a stationary level when a change of line took place another terrace cut.
The quartz boulders here again show the polishing effect by the glary sand and in places the sandstone is jilted due to what action.
