This cloudless view of northwestern Washington and southeastern British Columbia is a study in varied land-use patterns: the forested Olympic Peninsula and Cascade Range contrast with the wheatlands of the drier east side of the mountains. The checkerboard pattern of clearcut forest is accented by snow in the range east of Seattle. Major cities and seaports of the Pacific Northwest—Seattle, Tacoma and Vancouver—take advantage of the deep, sheltered channels.
The natural beauty and safe harbors of the region are products of tectonic processes acting on the western margin of North America. Mt. Rainier and Mt. Baker are just two in a line of recently active volcanoes extending from the Coast Mountains of British Columbia to Mt. Shasta in northern California. Strong earthquakes are also frequent, as exemplified by the Nisqually quake (magnitude Mw 6.8) of February 28, 2001, which rocked Tacoma, Seattle and the surrounding area.
