TOPOGRAPHY AND NATURAL CHARACTERISTICS 

 The surface of the county is mountainous on the southeastern 

 and northwestern borders, with a rolling upland through the cen- 

 ter. Several parallel ranges extend from the New Jersey line 

 northeast to the Hudson, ending in the rocky and precipitous bluffs 

 known as the Highlands. The Shawangunk Mountains, extending 

 northeast from the Delaware River, occupy the northwestern 

 corner of the county. The central portion of the county lying 

 between the two mountain systems is a rolling upland broken 

 by isolated hills and the deep valleys of streams. In the moun- 

 tains of the southern part lies a portion of the Palisades Inter- 

 state Park. 



The principal streams are as follows : Neversink River, which 

 flows along the west side of the Shawangunk Mountains ana 

 forms a tributary of the Delaware River; the Shawangunk Kill,
