Mount Rainier National Park, Washington
-- 70 miles southeast
Mount Rainier volcano (14,410 feet) dominates the landscape of a large part of western Washington.
It stands nearly 3 miles higher
than the lowlands to the west and 1.5 miles higher than the surrounding mountains.
The base of the volcano spreads over an area
of about 100 square miles, and lava flows that radiate from the base of the
cone extend to distances of as much as 9 miles. The
flanks of Mount Rainier are drained by five major rivers and their tributaries.
Mount Rainier National Park is located in west-central Washington,
approximately 108 kilometers (68 miles) south-southeast of Seattle and
150 kilometers (95 miles) north-northeast of Portland, Oregon.
The south entrance is accessible year round from U.S. Highway 12 and State
Highways 7 and 706, while the northeast entrance is accessible
on a seasonal basis via State Highway 410.
