A wildfire requiring the continued closure of a state highway through Chinook Pass may burn into the fall. Officials estimate full containment of the Norse Peak Fire — now at 1,540 acres — may not come until Oct. 1. State Route 410 — a main route from Central Washington into Mount Rainier National Park — will likely remain closed from Hells Crossing Campground to Chinook Pass through the end of the week to allow for tree removal and firefighting efforts, according to the state Department of Transportation.
