high angles. Proceeding eastward from the gorge the valley- 
increases in width. This gorge certainly marks the position of 
an old col. 
One half mile east of Fultonham Buckeye creek enters 
Jonathan creek from the south ; flowing in a broad open valley 
with rock walls sloping gradually down to the flood plain of the 
contained stream. Buckeye creek rises in Harrison township, 
of Perry county, flows northward into Newton township of 
Muskingum county, where it joins Jonathan creek. 
At the entrance of the valley from the south a broad 
gravel terrace stretches across Jonathan creek valley and ex- 
tends up the valley of Buckey creek. This terrace has an ele- 
vation of 25 feet above drainage. Jonathan creek has cut its 
way down through this deposit and is now running on a rock 
floor at this point. From the junction of Buckeye creek west 
to the col, Jonathan creek valley is narrow and gorge-like in ap- 
pearance. To the east from this point the valley is broader 
and gives evidence of being a direct continuation of Buckeye 
creek valley. 
From Newtonville to the Moxahala river the valley is 
filled in many places with gravel terraces. 
The south fork of Jonathan creek rises in the southeastern 
part of Perry county, receiving numerous tributaries it flows 
north through a broad open valley to its junction with its west 
branch below the village of Darlington. The Moxahala river 
at this point flows northward in a broad valley continuous with 
the valley of the south fork. 
At Darlington the river leaves its preglacial valley and 
breaking through a gorge empties into the Muskingum river 
three miles south of Zanesville. The abandoned valley of the 
Moxahala river filled up with gravel, continues north to Zanes- 
ville and opens into the Muskingum at the mouth of the Lick- 
ing river. 
Three miles south of Zanesville, between the buried chan- 
nel of the Moxahala river and Muskingum river and just to the 
north of the Moxahala gorge. Observation Knob rises to the 
height of 260 feet above the flood plain of the Moxahala.
