Snowplowing has stalled at least through Tuesday on Going-to-the-Sun Road as Glacier National Park crews work to repair portions of washed-out road shoulder at the foot of Lake McDonald.

That’s good news for hikers and bicyclists, who will have unlimited access to the road’s west side through Memorial Day weekend, but park spokeswoman Margie Steigerwald said Thursday they could encounter snow farther up the road.

Park employees reported one to three feet of high-elevation snow had fallen as cold, wet storms rolled through this week. An avalanche also came down on Sun Road near Haystack during the past few days.

Heavy rains at lower elevations caused a beaver dam to burst and dump debris onto Going-to-the-Sun Road about two miles from Apgar on Wednesday. That section of road is currently restricted to one lane while repairs continue, and Steigerwald said visitors should expect delays up to 20 minutes.

“Crews are working furiously to get it open to two lanes,” she said. “We’re optimistic that it will be open by the weekend, but it depends on various factors.”

Sun Road is still closed to vehicle traffic at Avalanche on the west side and at Jackson Glacier Overlook on the road’s east side.

While the weather isn’t forecast to be optimal for camping this weekend, campgrounds throughout the park will be open for Memorial Day weekend visitors.

All the loops of Apgar Campground are now open, along with Sprague Creek and Bowman Lake campgrounds on the park’s west side.

To the east, campsites are open at St. Mary, Two Medicine and Many Glacier.
