F. Terrace of ten feet. 
G. Terrace of thirty feet, the elevation from G to D 
being ninety five feet. 
Wells drilled for oil on the borders of this stream toward the Coshocton 
line show that this deposit of coarse gravel extends at least eighty-two 
feet below the bottom of the valley, and in one instance a log was struck 
at a depth of one hundred feet. Hence there is here disclosed a broad 
valley once filled with Drift to the depth of not less than two hundred 
and seventeen feet, through which a channel has been plowed one hun- 
dred and thirty-five feet, in depth, leaving a succession of terraces, 
the stream now flowing nearly one hundred feet above the bottom of the 
old gorge. Observations to be noted hereafter indicate even a much 
greater thickness of this deposit elsewhere.
