Worried that heavy snows could trigger avalanches, the Washington State Department of Transportation has temporarily closed State Route 410 at Chinook Pass and State Route 123 at Cayuse pass.
About 20 inches of snow have fallen on the passes since Friday, and several more feet are expected by tomorrow.
WashDOT maintenance crews are keeping an eye on conditions to see whether the road can be safely re-opened, or whether it should remain closed for the season, the department said in a news release.
“Chinook Pass, elevation 5,430, is closed from Morse Creek, five miles east of the summit to Crystal Mountain Boulevard, about 12 miles northwest of the summit. Cayuse Pass is closed within Mount Rainier National Park from the 4,675-foot Cayuse Pass summit to Stevens Canyon Road.” WashDOT said.
