A proposal to designate 215,000 acres of new wilderness areas in the Colville National Forest is drawing support from a broad coalition of forest users. The plan would expand the existing Salmo-Priest Wilderness in Northeast Washington and create new wilderness along the Kettle Crest, protecting six peaks that are each over 7,000 feet tall. The acreage represents some of the most remote, untouched land left in the lower 48 states. It’s home to grizzly bears, lynx and woodland caribou. And it’s an important wildlife migration route that connects the Rocky Mountains to the Cascades, environmentalists say.
