TOPOGRAPHY 



Jackson County occupies an inland trapezoidal area of approxi- 

 mately 77.2 km east and west, 77.2 km north and south on the western 

 boundary, and 108 km north and south on the eastern boundary. 

 Dicken's (1959:12) landform regions of Oregon divide the county into 

 two major mountain systems, the Cascade and Siskiyou mountains, 

 and one primary drainage system, the Rogue River and its tributaries. 



The Siskiyou Mountains, a part of the Klamath Mountain system, 

 form a dissected plateau more rugged than the Coastal Range of 

 Oregon. This range, running from east to west in the southern end of 

 the county, rises to elevations of over 1,524 m (Atwood, 1940:468). 

 Mount Ashland, elevation 2,296 m, is the highest peak in the Siskiyou 

 Mountains.
