Pacific Coast Ranges
The
Pacific Coast Ranges are the series of
mountain ranges that stretch along west coast of
North America from
Alaska to northern and central
Mexico. They are also known as the
Pacific Cordillera, especially in Canada where this term also includes the Rockies and Columbia Mountains and others. The character of the ranges varies considerably, from the record-setting
tidewater glaciers in the ranges of Alaska, to the low but rugged and
scrub-covered hills of southern
California, but the entire coast is consistent in dropping steeply into the sea, often resulting in photogenic views. Along the
British Columbia and Alaska coast, the mountains intermix with the sea in a complex maze of
fjords, with thousands of islands.
There are a handful of small coastal plains at the mouths of rivers that have punched through the mountains, most notably at the
Copper River in Alaska, the
Fraser River in British Columbia, the
Columbia River between Washington and Oregon, and the
Sacramento River in California, the last creating
San Francisco Bay.
From the vicinity of San Francisco Bay north, it is common in winter for cool unstable air masses from the
Gulf of Alaska to make landfall in one of the Coast Ranges, resulting in heavy
precipitation, both as
rain and
snow, especially on their western slopes.
