SR-20 is the state’s longest highway running 436 miles. It crosses Washington Pass at 5,477 feet and Rainy Pass at 4,875 feet in the North Cascades. It begins at US 101 at Discovery Bay on the Olympic Peninsula to US 2 near the Idaho state border in Newport. Rainy Pass is about four miles to the west of Washington Pass.
The passes are typically closed between November and April due to heavy snowfall.

During winter months, weather is usually cloudy, but due to high-pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.
The North Cascades Highway east of Washington Pass has the distinction of being among the top areas in the United States for most avalanche paths per mile of highway.
