The Missoulian has a news series called Stay close to home and rediscover Montana. Here’s a story by Rob Chaney from that series that begins… Less than a mile up the road from Avalanche Campground, the roar of a real avalanche overrode the burble of McDonald Creek. No animals were visible, but the scat of three major predator species spotted the asphalt. Now and again, the rain-washed breeze brought a musky whiff of something furry. With no car around you, the Going-to-the-Sun Road offers much more than a postcard view of Glacier’s interior. The “secret season” in spring and fall when most of the 32-mile westside highway is closed to motorized traffic turns the park’s most popular passage into a trail.
