TOPOGRAPHY AND NATURAL CHARACTERISTICS 

 The surface is mostly an upland, the ridges being broken by 

 the deep valleys of the streams. The highest summits, in the 

 southern part, are 500 to 800 feet above the valleys and 2,000 

 to 2,500 feet above tide. The slopes are usually too steep for 

 profitable cultivation. Toward the north the county becomes less 

 mountainous and spreads out into a hilly region. The Genesee 

 River flows northeast through the county, forming a deep valley 

 bordered by abrupt hillsides. The main ridges, which are parallel 

 to the river and about ten miles distant, form watersheds that 

 divide the waters flowing north from those flowing south. The 

 stream- east of the east ridge are tributaries of the Susquehanna 

 and those west of the west ridge flow into the Allegheny. 



The rocks of the county belong to the shales and sandstones 

 of the Portage and Chemung groups. In various localities the 

 sandstone furnishes an excellent building material, and in Rush- 

 ford it is quarried for grindstones. The soil on the uplands is 

 generally a heavy clay, frequently stony. In the valleys the soil 

 is mostly a gravelly loam and alluvium.
