TOPOGRAPHY AND NATURAL CHARACTERISTICS 

 The surface of the southern half has a general slope to the 

 north, while the northern half is level or gently undulating and 

 contains numerous marshes. The southern half is rolling and 

 rises gradually until it attains an elevation of from 1,000 to 

 1,200 feet above tide. Bluff shores border Skaneateles Lake, which 

 lies on the eastern border 840 feet above tide Owas.ro Lake near 

 the center is 770 feet above tide, its shores being generally bold 

 and in some places nearly precipitious. Along Cayuga Lake on the 

 western border, which is 387 feet above tide, the land slopes evenly 

 upward from its surface to the summits of the ridges separating 

 the lakes. Seneca River flows eastward through the lowlands that 

 form the northern half of the county. It receives Cayuga and
