BLANCHARD OR DEFIANCE MORAINE. 593 



brought in before this moraine was formed and were then taken up and 

 redeposited witli the moraine. 



The following detailed account of well sections and other exposures of 

 the drift begins in Geauga County near the great interlobate moraine and 

 follows the Defiance moraine westward. 



Mr. Ashcroft's well, on elevated land in Mimson Township, Geauga 

 County, penetrated 20 feet of till without reaching rock. A knoll near by 

 rises 20 feet above the well mouth. 



. At Leach's grocery, in southern Newberry Township, a well struck 

 rock at 50 feet. It is on comparatively low ground, 1,50 to 175 feet below 

 sandstone hills north of it. On these hills the drift seldom exceeds 30 feet 

 in depth. 



At Mrs. Reed's, 2 miles west of South Newberry, on gi'ound slightly 

 higher than that in the village, a well 159 feet deep did not reach rock. 

 It was mainly through sand, but there was a soapy clay at bottom. 

 Bowlders were encountered at 40 to 42 feet. 



At William McLaughlin's, 2 miles west of South Newberry and less 

 than one-half mile from Mrs. Reed's, a well penetrated a large amount of 

 blue till, the only thick bed of sand and gravel being in the lower 25 feet. 

 Rock was struck at 162 feet. 



About a mile west of McLaughlin's, on ground but little lower, rock is 

 exposed in shallow ravines, and southward from there along Bridge Creek, 

 in Auburn Township, rock is exposed to a height of 25 feet above the creek. 

 Immediately west of this creek, on ground but a few feet higher, wells 70 

 to 80 feet in depth do not reach rock. 



Near Auburn Center ravines 30 to 40 feet deep do not expose rock. 

 The drift in knolls near Auburn Center contains much gravel, but below 

 the level of the base of the knolls there appears to be a sheet of till. 



In the northwest part of Auburn Township G. A. Richards has a well 

 on comparatively low ground which does not strike rock at a depth of 65 feet. 



A well at Oscar Niece's, in Brainbridge Township, southwestern 

 Geauga County, is reported by the well di-iller, R. A. Dayton, of Burton, 

 Ohio, to have penetrated 115 feet of drift. A well 3 miles west of Bain- 

 bridge Center, near the line of Geauga and Cuyahoga counties (owner's 

 name not known), also reported by R. A. Dayton, penetrates about 200 

 feet of drift.
