A potential rock slide could keep Cayuse Pass (SR 123) closed through the 2007 Thanksgiving holiday.
Two large rocks are perched above the highway inside Mount Rainier National Park and the ground supporting these rocks is saturated. Several rocks fell onto the highway on Tuesday, Nov. 13.
The road will remain closed until federal geotechnical experts assess the danger and craft a plan to remove the unstable rocks.
SR 123 is closed from Stevens Canyon Road intersection to the SR 410/SR 123 junction. SR 123 is not a heavily traveled highway. Fewer than 1000 vehicles each day use the pass. Travelers may use Chinook Pass (SR 410) to get to their holiday destinations.
