Chinook Scenic Byway

From Wikipedia, the free encyclopedia

Chinook Scenic Byway is an All-American Road in the U.S. state of Washington. It consists of the segment of State Route 410 through the Cascade Range between Enumclaw and Naches. Also known as Mather Memorial Parkway, Chinook Scenic Byway passes through Mount Rainier National Park, crosses Cayuse Pass at 4,700 feet, and crests at Chinook Pass on the east border of Mount Rainier National Park at 5,432 feet.

Chinook Scenic Byway between the Northwest park entrance and 5 miles east of Chinook Pass usually closes in late October. This is due partly to the avalanche danger, and partly to the difficulty of keeping the roadway open. Wintertime snowfalls regularly exceed 15 feet, and are removed using rotary snowplows. The roadway is usually opened in mid- to late June.
