16 THE PREGLACIAL DRAINAGE OF OHIO. 



DISTRIBUTION OF THE PRESENT DRAINAGE. 



The distribution of the present drainage is shown on the map 

 (Plate I) in black. The Ohio is the major stream and this 

 crosses the region in a general southwesterly direction. The 

 next larger stream is the Muskingum which C the Ohio 



on the northern side at Marietta. Next in importance is the 

 Hocking which enters also on the northern side of the Ohio 

 and has a general southeastern direction, rather abnormal to 

 the course of the Ohio. 



On the southern side of the Ohio the Little Kanawha enters 

 at Parkersburg. East of the Little Kanawha lies the consid- 

 erable basin of Middle Island Creek, which enters the Ohio 

 just above St. Mary's. To the west and southwest of the Little 

 Kanawha is the basin of the Big Kanawha. The modifications 

 which have taken place on the Big Kanawha are discussed by 

 the author and by Mr. Frank Leverett in the Denison Univer- 

 sity Bulletin, Volume IX, Part 2, Articles III and IV. 



On the northern side of the Ohio and east of the Muskin- 

 gum are the valleys of the Little Muskingum and Duck Creek, 

 both tributary to the Ohio a little above the mouth of the Mus- 

 kingum. West of the Muskingum and between it and the 

 Hocking is the somewhat branched system of the Little Hocking. 

 This has two main branches, the North Branch and the East 

 Branch. 



East of the North Branch of the Little Hocking and north of 

 the Big Hocking is the basin of Federal Creek. This is a very 

 peculiar stream as it flows in almost a circular course with many 

 radial tributaries, those on the north side of the circle being 

 much longer than those on the south side. 



South of the lower portion of the Hocking is the Shade 

 River system with its three main branches, East, Middle and West 

 Forks. 



The only other considerable stream in the region is Wolf 

 Creek. This rises in northern Morgan county and flows south- 

 ward and eastward and enters the Muskingum at Beverly. A 

 short distance above its mouth it receives a tributary of consid-
