TOPOGRAPHY AND NATURAL CHARACTERISTICS 



The surface is a hilly upland, separated by deep valleys into 

 distinct ridges having -a general north and south direction. The 

 valleys deepen toward the south, where the hills rise 800 to 1,300 

 feet, reaching an altitude of 2,500 to 3,000 feet above tide. Many 

 of the hills, though -arable to their summits, are too steep for 

 profitable cultivation. Toward the northern border the surface 

 is less mountainous, and the hills spread out into high rolling 

 uplands. Allegheny River enters the southeast corner of the 

 county from Pennsylvania, flows northeast until it reaches the 

 center, and .there turns southwest into Pennsylvania. This river 

 and its tributaries form the principal drainage of the county. 

 Cattaraugus Creek forms the northern boundary and Gonewango 

 Creek drains the west side of the county. On all the streams are 

 numerous falls. 



Drift deposits are found to some extent throughout the county, 

 and beds of clay, alluvium, and muck are found in limited quanti- 

 ties in the valleys. The soil in the valleys is generally yellowish 

 loam composed chiefly of disintegrated sandstone and shale. On 

 the uplands it is clay alternating with sand and gravel, and under- 

 laid by hardpan.
