324 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



is now about 400 feet deep, and was perhaps 100 feet deeper previous 

 to the deposition of glacial gravels by streams from the Wisconsin ice 

 margin. 



In southern Fayette County, near Everton, moraiuic features are well 

 displayed and the structure of the drift is variable. Several gravel knolls 

 occur between Everton and Alguina, and also northwest of Everton, but the 

 greater part of the drift is till, both at the surface and in well sections. In 

 northeastern Fayette and southwestern Wayne counties there is but little 

 gravel on the uplands. The soil is not so loose and loamy as is usually the 

 case in morainic belts, and is called by the residents "cold clay." The 

 thickness of drift here is variable. One well near the county line, a mile 

 or more east of Waterloo, is about 80 feet deep, and does not strike rock. 

 About 4 miles southeast of Waterloo and east of the West Whitewater 

 there are rock quarries. Along the West Whitewater in Fayette and Wayne 

 counties there is a gravel plain one-half mile to a mile wide, which has a 

 deep deposit of glacial gravel. The bottom has been reached only in the 

 few gas-well borings that have been made along it. Several borings along 

 this valley, both within the moraine and south of it, that reach rock are 

 discussed below, beginning near the head of the stream at Dalton, Wayne 

 County, on Nettle Creek, one of the main tributaries. At Dalton the thick- 

 ness of drift in the gas well is 2 40 feet and the altitude of the well mouth is 

 about 1,100 feet. There was a slight amount of gravel at the surface, but 

 the greater part of the drift was found to be till, mainly of a blue color. 

 Dr. E. H. Thurston, of Hagerstown, gave the following information con- 

 cerning wells in that village, the altitude of which is about 1,000 feet: 

 Eight gas wells have an average of about 100 feet of drift, the least amount 

 being 78 feet. The upper 50 feet is largely gravel, the remainder till. At 

 Cambridge (whose altitude is about 940 feet) two wells show about 100 

 feet of drift. One has 10 to 15 feet of gravel at top, the remainder of the 

 drift being blue till. A reliable record of the second well was not obtained. 

 There are outcrops of rock in Whitewater Valley in that vicinity at about 

 the level of the wells. A mile west of Cambridge, and at 70 feet higher 

 altitude, a well penetrated 160 feet of drift; the upper and lower portions 

 of this were sand and gi'avel, a considerable amount of till intervening. 

 At Dublin, 2 miles west of Cambridge, and at an altitude 115 feet higher, 

 a gas well penetrated 300 feet of drift. At Connersville several deep wells
