OLD UFPEfl TUSCARAWAS DRAINAGE SYSTEM. 165 



but farther up the valley, near the mouth of Jerome Fork, it passes through 

 a narrow channel among the hills. The old valley lies west of this narrow 

 channel. Whether it connects at the north with Jerome Fork has not been 

 ascertained. 



KILLBUCK CREEK. 



This creek now drains the western part of Wayne and the greater 

 part of Holmes County, flowing southward into the Walhonding a short 

 distance above the head of the Muskingum. It apparently is flowing in 

 the main in the reverse direction from its old course. The headwater 

 portion, down to within 8 or 10 miles of Wooster, found its old line of 

 discharge northward jDast Lodi to the Black River, a tributary of Lake Erie. 

 A boring recently made in this old valley near Lodi is reported by Todd 

 to have reached a level less than 700 feet above tide without entering rock, 

 the depth of the boring being 210 feet. 



It is quite certain that the old valley which leads northward along the 

 Killbuck, as above noted, from Shreve to Wooster did not continue along 

 this creek beyond Wooster, for there is only a narrow valley for several 

 miles above Wooster, the width between rock bluff's being in places less 

 than one-fourth of a mile. The continuation of that old valley (the old 

 Mohican) was probably eastward, as suggested by Todd. 



A large part of Killbuck Valley apparently once discharged northward 

 to the old Mohican, for there is a marked narrowing of the valley in passing 

 southward down the present stream. Beneath the glacial gravel the valley 

 is also filled with a fine silt, which was probably deposited in a pool of water 

 that found outlet to the south only after rising above the level of a divide 

 on the lower course of the creek. This silt is a conspicuous feature below 

 Millersburg at least to the village of Killbuck, and seems to indicate that 

 the divide was south of that village. That portion of the valley is narrow 

 and winding, as if it had once constituted the headwaters of drainage lines, 

 but the precise position of the old divide was not determined. After this 

 divide had been surmounted the south-flowing stream carried down the 

 valley to the Muskingum a large amount of gravel of Wisconsin age 

 that is now preserved in the form of terraces on the valley borders. 



OLD UPPER TUSCARAWAS DRAINAGE SYSTEM. 



It was noted above (p. 158) that the Tuscarawas crosses an old divide 

 between the mouth of One Leg Creek and Canal Dover. This is one of
