TOPOGRAPHY AND NATURAL CHARACTERISTICS 



Putnam County embraces nearly all of the Highlands east 

 of the Hudson. The mountains consist of several steep, rocky 

 ranges extending in a northeast and southwest direction and 

 separated by deep, narrow valleys, the principal of which are 

 Peekskill Hollow and Canopus and Annsville valleys. 



The county is watered by the principal branch of Croton River 

 and several smaller streams. Among the mountain valleys are 

 numerous picturesque lakes, the largest of which are lakes 

 Mahopac, Oscawana and Glcneida. 



In the valleys the soil is a productive sandy loam, but the 

 mountains are rocky and unfit for cultivation.
