G. F. Wright—Glaciated Area of Ohio. 47 
MoreE DETAILED ACCOUNT. 
Through Columbiana county as in the adjoining counties of 
Pennsylvania, south of the heavy deposits of till there is a 
fringe from one to three miles wide. Over this margin there 
are scattered evidences of glacial action, consisting of granite 
bowlders and patches of till here and there upon the highlands, 
at an elevation of from three hundred to five hundred feet above 
the Ohio River. North of this fringe the till is continuous and 
everywhere of great depth. At Palestine, on the eastern edge 
of the county, and at New Alexundria, near the western side, 
wells are reported in the till fifty feet deep. New Alexandria 
is upon the highest land in that part of the country, and the 
glacial deposits are marked in moderate degree by the knobs 
and kettle-holes characteristic of the moraine upon the south 
shore of New England. A mile or two west of Canton, in 
Stark county, the accumulations of glaciated material are upon 
a scale equal to anything upon Cape Cod. The northern part 
of Holmes county is covered with till which is everywhere of 
great depth, and in numerous places near the margin displays, 
though in a moderate degree, the familiar inequalities of the 
New England moraine. After the southern deflection in Knox 
county, the glaciated region is entered near Danville, from the 
east, on the Columbus, Mount Vernon, and Akron Railroad, 
through a cutin till a quarter of a mile long, and from thirty 
to forty feet in depth. At the old village of Danville near by, 
upon a neighboring hill, wells are reported as descending more 
than a hundred feet before reaching the bottom ‘of the till. 
Through Licking county, both north and south of Newark, the 
depth of the glacial envelope is great up to a short distance of 
its eastern edge. At the old reservoir in Perry county, the 
distinct features of a moraine come out. The hill upon which 
Thornville is built is a mass of glaciated material in which 
wells descend from thirty to fifty feet without striking rock. 
This is upon the highest land of the vicinity. The reservoir 
itself seems to be in a great kettle-hole or moraine basin. All 
through Fairfield county, the glacial accumulation is of a great 
depth down to a very short distance of its margin. But per- 
haps the most remarkable of all the portions of this line in Ohio 
is that running from Adelphi, in the northeast corner of Ross 
county, to the Scioto River. The accumulation at Adelphi is 
more than two hundred feet, and continues at this height for 
many miles westward. Riding along upon its uneven summit, 
one finds the surface strewn with granite bowlders, and sees 
stretching off to the northwest the magnificent aud fertile plains 
of Pickaway county, while close to the south of him, yet sepa- 
rated by a distinct interval, are the cliffs of Waverley sandstone, 
rising two hundred or three hundred feet higher, which here
