Oregon Coast Range
The Oregon coast extends in a general north and south direction for roughly 300 miles, and
consists of long stretches of sandy beach broken occasionally by lateral spurs of the
Coast range, forming small coastal bays.
Parallel with the coast, about 20 miles inland is an irregular chain of hills know as
the coast range. Although not very high, (greatest peak at 4097 feet), the coast
range has numerous lateral spurs, especially towards the west.
Several rivers such as the Nehalem Coquille, Rogue, and Umpqua cut
their way through the coast range to reach the Pacific ocean.
The northern two-thirds of the Oregon Coast range is bordered on the east by the
Willamette Valley, a region about 200 miles ling and about 30 miles wide, and the
most populated portion of the state, and is easily defined, but in the south, near
the Rogue river, it merges apparently with the Cascade and the Sierra Nevada mountains
in a large complex group called the Klamath mountains, lying partly in Oregon and partly in California.
