Heavy rain may cause problems for crews in Glacier working to open one of Glacier's main attractions, Going-to-the-Sun Road.

16 miles of Going-to-the-Sun Road is open right now for visitors, to the Avalanche viewing spot, but crews are still working away at Logan Pass, at the top of the road.

"Right now the west side plow crew is pioneering near the Triple Arches area, and on the east side the crew is near Siyeh Bend," said Glacier spokesperson Denise Germann.

Photos from the park show the crew plowing Going-to-the-Sun Road, which is one of the most dangerous jobs in the world.

Right now, tourists are taking advantage of the weather and biking the path that is open.

"You can drive as far as Avalanche and then you can hike or bike, basically to the Loop during the day and after 6 o'clock and on weekends, it's unrestricted," said Germann.

Workers explain that weather is always unpredictable at Glacier National Park, so if you're making a trip, you should always come prepared.

"That includes to have appropriate clothing, layers of clothing, footwear, water and snacks. And always let someone know where you're going and when you plan to return," explained Germann.

For all those visitors getting anxious to make a trip on Going-to-the-Sun Road, the earliest it will be open to Logan Pass is June 20 from the east side, but the west side will depend on the weather.
