596 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



moraine, rock is struck at 10 to 15 feet. The thickness on the moraine is 

 probably as much greater as its relief above the outer border district — 

 about 30 feet. 



At the village of Sullivan, also just south of the moraine, a well at the 

 Sullivan House, 35 feet deep, does not reach rock; and many other wells in 

 that vicinity obtain water from the drift at 25 to 30 feet. Blue till is encoun- 

 tered at about 10 feet and extends to the water vein, which is usually from 

 gravel. On the north slope of the moraine, 3 or 4 miles northwest from 

 Siillivan, there are exposures of rock in the shallow ravines. The thick- 

 ness of drift along the crest in this vicinity probably averages 50 feet, as it 

 stands fully 30 feet above the bordering plains. 



At Nova the town well strikes rock at 25 to 30 feet. This village 

 also is on the jjlain south of the moraine. 



Along the inner till ridge, in Spencer and Huntington townships, rock 

 is struck at 20 to 30 feet, and outcrops are found in shallow ravines. In 

 Spencer Center there is a cutting 15 feet deep, where the ridge is crossed 

 by the Wheeling and Lake Erie Railroad, which shows yellow till from 

 the top nearly to the base, and there blue till sets in. A few rods south 

 is a ravine in which rock appears at a level about 20 feet below the base 

 of the cutting. 



In the vicinity of New London the drift is rather thick. Dorr Smith, 

 a well driller, has made several wells in the village which have passed 

 through 95 to 115 feet of drift. Many wells obtain water in gravel below 

 till at 75 to 95 feet. It is Mr. Smith's opinion that there is a buried 

 channel leading from New London northeastward past Wellington, for rock 

 is not struck along this line at so shallow depth as it is on either side of 

 the line. A well at Bushnell Post's, 2 miles north of New London, appears 

 to be in this channel, since it has over 100 feet of drift; and two wells in 

 the southwest corner of Brighton Township, Lorain County, also appear to 

 be in the channel — one at D. S. Stocking's having 98 feet, and the other 

 at C. D. Stocking's 88 feet of drift. In C. D. Stocking's well there is 68 

 feet of till, beneath which 20 ^eet of fine sand was penetrated. Near 

 Rochester, about 2 miles southeast of Mr. Stocking's and at about the same 

 altitude, James Horton has a well which struck rock at only 55 feet, and 

 rock is struck in shallow wells a mile or so west of Mr. Stocking's. In 

 WelHngton there are several wells which penetrate 90 to 105 feet of drifr.
