Glacier country's steep terrain, heavy snowfall and ever-changing weather are key elements for one of Nature's most awesome and deadly occurrences in the snow avalanche. Responsible backcountry travelers should possess the skill and knowledge to assess avalanche conditions. Always carry shovels, probe poles and avalanche beacons. Bi-weekly avalanche advisories are issued during winter by the Northwest Montana Avalanche Center. Snow conditions on the east side of Glacier National Park vary considerably and winds can blow a cross-country ski route clear of snow at any time.
Some routes cross onto the Blackfeet Indian Reservation.
The tribe requires a free cross-country skiing permit obtainable at the tribal fish and game office in Browning. Increasing levels of outdoor recreation are resulting in significant impacts on America's wildlands. The national Leave No Trace program promotes responsible outdoor use ethics. Backcountry campers in Glacier country should carefully select gear to minimize bulk and weight, but maximize safety and comfort. Your comfort level will be greatly enhanced if you take clothing that keeps you warm and dry and that can be layered.
