Tobbles occur in the rock in the stream bed at the first road corner beyond Floyd's Fork. The exact geological horizon is not tknown but is probably Lower Silurian, below the Clinton. The largest pebble is 1 1/2 inches long. The color of the pebbles is bright blue 10 At the next road corner going a little west of south is Flat Rock Church. In the stream west of the church the Clinton is exposed. It is two feet thick, and its color is reddish, which resembles that at Sinclair's farm. Two feet lower down is the very fine grained dark blue limestone layer with gas stripped, which blue is especially crowded with by grains. Further down the stream the typical Madison rock is exposed. 11 Going from Flat Rock Church 2 miles westward and then 1/3 mile northward, the farm of Levi Collins is reached. Here the Clinton on the road side is reddish varying to silicious and is 2 feet thick. 8 Half a mile further north, in a stream bed west of the road in the Ike Collins farm, just south west of Jim Ward's farm house, the Salurian colored Clinton is exposed. It is here 5 feet to 5 feet 4 inches thick. This re- markable increase in the thickness of the Clinton seems to be accom- pañied by a similar increase in the thickness of the Lower Osgood shale, judging from exposures just south of the Jim Ward house but my measure- ments were made. Exposures here are favorable for a section including rocks up to the Sau- nel formation. Frequent ex- posures of Clinton occur on the road returning to Pewee Valley.
