CLEVELAND MORAINE. 625 



It passes about 3 miles south of the village of Ashford Hollow, 1 to 2 miles 

 south of the village of West Valley, and 2 to 3 miles north of Machias. 



From near the head of Ischua Creek, about 4 miles southwest of 

 Machias, another moraine leads eastward, passing just south of Machias, 

 and continuing about 3 miles beyond that village. It there becomes obscure, 

 but seems to be continued in a belt that sets in 4 or 5 miles farther east, 

 near Fairview, and leads southeastward past Rushford to the Genesee Valley 

 at Caneadea. Whether this moraine is a member of the same system as 

 that to which the Cleveland belongs is not determined. It may be a 

 correlative of an earlier moraine, but its close association with the supposed 

 Cleveland moraine in the few miles in which it is well developed seems to 

 justify its consideration in connection with that moraine. From Machias 

 eastward to the Genesee the two moraines are separated by a space of but 

 4 to 8 miles. 



Returning to the meridian of Machias, we find that the northern or 

 supposed Cleveland moraine takes an eastward course to Clear Creek (a 

 southern tributary of Cattaraugus Creek) at Sandusky. It there swings 

 northeastward and rises to the elevated divide between the head of Catta- 

 raugus Creek and Wiscoy Creek, a western tributary of Genesee River. 

 On this divide it turns southeastward, but extends a spur northward along 

 the divide to the next morainic system. The village of Eagle stands near 

 the outer border of the moraine at the place where it turns to the southeast. 



The moraine is strong for about 3 miles east of Eagle. It is then 

 poorly defined for a couple of miles. It becomes strong again in Cold 

 Creek Valley, in northeastern Ceuterville Township, and leads down the 

 south side of that valley to the Genesee, coming to that river between the 

 villages of Houghton and Fillmoi'e. 



RANGE IN ALTITUDE. 



The course of the Cleveland morainic belt being across a hilly region, 

 there are frequent fluctuations in altitude. In many cases the moraine 

 makes a rise of 200 to 300 feet within a space of 1 to 2 miles, and occasionally 

 an even greater rise in an equally short distance. The following table 

 presents the principal fluctuations.
