244 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



South of Red Bank Junction, on the west side of the river, a naiTOw 

 remnant of a terrace was found about 280 feet above the river, which also 

 may be glacial, though Canadian rocks were not found in it. 



Opposite Templeton, on the west side of the river, a glacial terrace, 

 with coarse gravel containing a few Canadian rocks, has an altitude of about ' 

 250 feet above the river. Rounded pebbles occur on the slope above this 

 terrace up to a level about 50 feet higher. 



Between Templeton and Kittanning there are several remnants of a 

 deposit of glacial gravel standing about 250 feet above the river, as well 

 as terrace-like remnants at lower altitudes, apparently reduced from the 

 original level of filling. The rock shelves on which the gravel rests stand 

 only 150 to 200 feet above the river. The original depth of the gravel 

 was probably 75 feet or more. 



West of Kittanning there is a deposit of glacial gravel, standing about 

 250 feet above the river, in which wells have reached a depth of 30 feet 

 without entering rock. A mile south of Kittanning, at a similar altitude, 

 wells reach a depth of 40 feet in gravel. A short distance farther south, on 

 the south side of Garretts Run, the thickness of the gravel is 70 feet or 

 more. It contains coarse beds and includes a few Canadian rocks (granite 

 and quartzite). This deposit has an altitude of about 235 feet (aneroid) 

 above the river. On a continuation of this deposit immediately back of 

 Ford a channel was found along its east border next the bluff, which 

 seems to have been made by a stream. It is much narrower than the 

 present river channel, being only 50 to 75 yards in width, and probably 

 carried only a, part of the old river. Notwithstanding its great altitude 

 above the present river, the banks of the channel are clearly defined. The 

 terrace here is probably reduced from the original level of the gravel filling, 

 for pebbles appear on the slope back of it up to a level about 20 feet above 

 the terrace or 255 feet above the river. 



On the west side of the river an old oxbow channel is found east of 

 North Buffalo at an altitude only 120 feet above the river. It is in a 

 terrace which stands 30 to 40 feet higher, but the terrace, as well as the 

 channel, is evidently far below the original level of gravel filling-. There 

 are extensive terrace remnants on the west side below North Buffalo, but 

 they all seem to be cut down below the original level. On the east side, 

 also, there has been much reduction from the original level, though small
