Age of Licking Narrows 
From these facts it follows that the relation of the ice-sheet to 
the topography must have been such that the outflowing waters 
; were ponded in valleys A and B at one level, in valley C at a dif- 
ferent level, and were not ponded at all in valley D. 
Old water channels. Three-fourths of a mile south of Claylick 
there is a broad sag (Channel K, fig. i) connecting valleys A and 
B at the level of the terraces described above. The terrace in 
valley A is slightly higher than that in valley and slopes gently 
eastward through this sag into the latter valley and is continuous 
with the terrace there. That this sag was the outlet of the lake 
in valley A at the time of the formation of the terrace system is 
evident. 
The cemetery of the town of Claylick is situated on the bench 
marked L (fig. i) and shown in the photograph (fig. 3). It must 
} have been carved out of the hill slope by the overflow of the lake 
! in valley Ay which at some time evidently 'flowed across it. This 
I course must have been taken by the stream after its diversion from 
the sag Ky but before the complete withdrawal of the ice, whose 
front must have served as one side of the outflow channel at L, 
After the retreat of the ice sheet from that point the stream slipped 
off this bench and its course can be seen in a broad curve in the 
Fig. 3. Bench “LA near Claylick, Ohio.
