The Winter Terrain Atlas provides valuable visual terrain information to backcountry users of Mount Revelstoke and Glacier national parks. It is designed to provide a common language for place and run names and to assist with trip planning and rescue situations. The Winter Terrain Atlas also helps backcountry users identify Winter Permit Area boundaries.

Avalanche Canada provides daily avalanche forecasts for the Glacier National Park area. It is important to check the forecast before heading out into the backcountry. Avalanche Forcast can be found on the Avalanche Canada website.
A good knowledge of avalanche safety is essential when venturing into the backcountry. Avalanche Canada offers a variety of courses to help you learn about avalanche safety. AvySavvy is an online resource that provides free avalanche safety training. It is a great way to start.
It is strongly recommended to have at least the Avalanche Skills Training 1 (AST 1) course before heading into the backcountry. The AST 1 course provides an introduction to avalanche safety and teaches you how to recognize avalanche terrain, understand the avalanche bulletin, and perform a companion rescue.

Trans-Canada Highway (Highway 1) is the main highway that runs through Glacier National Park. It is important to check the road conditions before heading out into the backcountry.

Cellular service is limited in the backcountry. It is recommended to carry a radio for communication in case of emergency. FRS (Family Radio Service) and GMRS (General Mobile Radio Service) are two-way radio services that are available for use in Canada. FRS radios are limited to 0.5 watts and have a maximum range of 2 miles. GMRS radios are more powerful and have a maximum range of 5 miles. You can find the list of FRS and GMRS frequencies on the RadioReference Wiki website. Store-bought radios are pre-programmed with these frequencies.
Glacier National Park has a repeater on 166.380 MHz. I have not been able to find more information about this repeater, but it is likely used by Parks Canada staff for communication in the park.
