162 GLACIAL FOEMATIONS OF ERIE AND OHIO BASINS. 



of the North Fork of Licking River east of Homer, where it was joined by 

 a drainage line leading in from the northeast past Danville and G-ambier. 

 The united waters then passed westward into the Scioto Basin. It is not 

 yet known how much of the basin of Mohican Creek was tributary to this 

 line, but judging from the small size of the old valley at Danville it was 

 probably only a small part. Possibly it included only the section between 

 the high ridge at the north line of Knox County and a narrow part of the 

 Moliican Valley a short distance below the point where the old valley turns 

 off toward Danville, a section about 12 miles in length. This leaves a 

 stream about 8 miles in length on the lower course of Owl Creek and a . 

 similar stream on the lower course of Mohican Creek to form the old 

 headwaters of the Walhonding River. 



CHANGES IN CLEAR FORK OF MOHICAN CREEK. 



Clear Fork drains a small district imme'diately north of the drainage 

 basin of Owl Creek. Its headwaters are in eastern Morrow and southwestern 

 Richland counties in a moraine that forms the east border of the Scioto 

 Basin. The moraine has in that vicinity an altitude of 1,300 feet or more. 

 From the moraine the several headwater streams flow east and southeast 

 and unite a short distance west of Bellville. The stream then passes into a 

 more elevated hilly region whose highest points are nearly 1,600 feet above 

 tide. The valley at the west border of these hills is more than one-half 

 mile in width, but upon passing eastward down the present stream it 

 narrows and finally becomes a contracted gorge just above Newville, where 

 the rock bluffs are scarcely 100 yards apart. This evidently marks the 

 position of an old divide. 



Below this divide the old di-ainage was eastward, as at present, but it 

 apparently was a short distance north of the present stream, along a line 

 now followed in part by Black Fork. The present course is across points 

 on the slope south of the old valley. This departure from the old line is 

 due to a moraine that follows the north side of the present stream from 

 Perryville eastward and prevents the stream from following the old line. 



CHANGES IN OTHER HEADWATERS OF MOHICAN CREEK. 



There are several other headwater tributaries of Mohican Creek in 

 Richland and Ashland counties which, like Clear Fork, have their sources 

 outside of the highest country included in their basins. The most impor-
