TOPOGRAPHY AND NATURAL CHARACTERISTICS 



The surface consists principally of an upland broken by a series 

 of ridges extending north and south. That part of the county 

 south of Dry den, Ithaca, and Enfield Center is high and rolling, 

 elevations rising from 1,900 to 2,000 feet in the townships of 

 Dryden, Caroline, and Xewfield. In the northern part the up- 

 lands are more gently rolling and are cut by several deep valleys 

 like those of the Salmon and Owasco creeks. 



Cayuga Lake occupies a deep gorge in the northwestern part 

 of the county and receives the drainage of the greater portion of 

 the area, the principal streams being Salmon, Fall, Cascadilla, 

 Sixmile, and Taughannock creeks and Cayuga Inlet. The south- 

 ern part is drained by several branches of Owego Creek, a tribu- 

 tary of the Susquehanna. In their passage from the upland the 

 streams have worn deep gorges, and many beautiful waterfalls 

 may be seen within that section of the county adjoining the head 

 of Cayuga Lake. The Taughannock Falls, 215 feet in height, 

 rank as the highest true waterfall in New York State. 



The soil in the northern half of the county is generally a grav- 

 elly or clayey loam formed by drift deposits, while a largo portion 

 of the southern half is a slaty loam derived from disintegration, 

 more or less modified by glacial deposits.
