although no stream trash was certainly identified upon its surface which 

 is about 130 feet above the river. Scioto Heights rises, with about a 

 45° slope, to 510 feet above low water in the Ohio. Here the Ohio 

 Valley is estimated at one and a half to two miles wide. The valley 

 widens perceptibly above the mouth of Kinniconick Creek which meets 

 the Ohio from the south west flowing in the opposite direction to that 

 of the Ohio. Passing up the Ohio toward Portsmouth the valley of 

 the Ohio seems to be directly continuous with that of the Scioto. The 

 Scioto valley at its mouth is some wider than the Ohio immediately be- 

 low. If a stranger unfamiliar with the facts would not observe the 

 volume of the waters in the Ohio above the mouth of the Scioto and 

 the latter stream, but would base judgment on the form, size and di- 

 rections of the valleys, the Scioto would be taken as the continuation 

 of the Ohio Valley as it is seen approaching the junction of these 

 streams both from the Scioto and lower Ohio valleys. The Ohio valley 

 immediately above Portsmouth is scarcely a mile wide while bold cliffs 

 of Waverly shales and sandstones face the stream on both sides of the 

 valley. 



A few miles further up the river the valley grows wider and re- 

 ceives a considerable tributary, Tygart's Creek, from the southwest. 

 At this point also the valley bears to the northeast toward Sciotoville 

 and in this direction the valley also increases in width. 



At Sciotoville begins the great bend in the Ohio valley towards 

 the south and southeast. Here also enters from the north the Little 

 Scioto river which as will be shown later is a reversed stream with a 

 deep valley cut out of a former drainage system. 



Continuing up the Ohio valley almost due south to Greenup the 

 valley is much wider. The bordering hills do not rise to the level of 

 the cretaceous peneplain until some distance back from the immediate 

 valley walls. The travelers on the river steamers do not seem to be so 

 shut in but enjoy a more open and extended view or may do so if their 

 eyes are open to the world around them. 



The old drainage level valley known as " The Flat Woods " which 

 runs parallel to the Ohio on the Kentucky side back of Ashland will 

 not be described. The reader is referred to the literature on the sub. 

 ject as found in Kentucky Geological Survey, described by Mr. Lyon ; 

 Ohio Geological Survey by E. B. Andrews Vol. II, Page 441 ; by 

 Prof, G. F. Wright, Vol. V, Page 765.
