most the exact duplicate of one of the trips taken during the study of 

 the region. The line of this proposed trip is indicated on the map. 

 (Plate II.) 



Starting from Bainbridge, Ross county, our first point of obser- 

 vation will be the high quarry hill A just south of the town. This hill 

 capped with Waverly freestone rises 450 feet above Paint creek, to 

 an elevation 1180 feet A.T. A view to the north across the valley of 

 Paint shows the hills forming the north wall of Paint valley over a 

 mile away and rising nearly to a level with the observer. To the 

 east extends the very deep and broad valley of Paint on its way to 

 the Scioto. Large drift deposits fill the valley along its northern side, 

 often rising to 150-200 feet above the creek. There are numerous 

 terraces in the valley, and the creek is undoubtedly 150 feet above the 

 rock floor of the valley. Westward the valley is distinguishable as a 

 very evident trough of preglacial origin as far as the junction of 

 Paint and Rocky Fork. Beyond rises very rapidly the drift-buried 

 tableland of northern Highland county; and the well defined pregla- 

 cial valley of Paint seems to end, suggesting some mteresting prob- 

 lems in that direction, for somewhere in that locality we must look 

 for the preglacial channel of reversed Brush creek. 



As the view to the south is cut off by timber, we return to the 

 pike and pass westward about one mile, where the view to the south 

 shows a break in the high Waverly capped hills, and their place is 

 taken by others of somewhat less altitude. From the pike along the 

 creek the change in altitude would hardly be noticed ; but as these 

 hills are destitute of timber, they offer a prospect of an extended 

 view to the south, and with this hope the ascent of the highest is un- 

 dertaken. On reaching the summit at B, 190 feet above the river, 

 and 990 feet A. T., it is found that this hill only concealed from the 

 view on the pike still others just beyond, which rise just enough 

 higher to obstruct the coveted view southward. 



Our surprise is great, v/hen almost on the summit of the next 

 hill we find a ground-hog burrow, and the material revealed indicates 

 glacial drift. The first thought is that this can not be drift at an eleva- 

 tion of 200 feet above the creek, and on the south side of Paint val- 

 ley. A glance southward shows a comparatively level plain and not 

 a rolling hill country as might have been expected. 



This then is the extreme northern edge of the Beech Flats. What 

 had concealed the real nature of these drift hills was their steep
