Chinook and Cayuse passes closed for the season

Chinook and Cayuse passes have closed for the season after the state Department of Transportation reviewed a snowy forecast and assessed the avalanche risk.

Due to heavy snow accumulation on the roadway, DOT crews temporarily closed Chinook Pass just after 7:30 a.m. on Saturday. Crews assessed the stability of the hillside on Sunday morning, and determined the avalanche risk is too great to allow traffic to safely cross Chinook Pass and Cayuse Pass.

Since Friday, Chinook Pass has received more than three feet of snow. More snow is forecast.

The Highway 410 Chinook Pass closure points are at Morse Creek (five miles east of the summit) and at Crystal Mountain Boulevard (eight miles northwest of the summit). Access to the Crystal Mountain Ski Resort from Highway 410 remains open.

DOT and the Mount Rainier National Park staff agreed to close Highway 123 (Cayuse Pass) for the season. The highway is closed within Mount Rainier National Park from the 4,675-foot Cayuse Pass summit at the junction of Highways 410 and 123 to Steven Canyon Road. DOT closes each pass for the winter due to high avalanche risk and hazardous driving conditions.
