If you want to get into the backcountry this winter, it’s important that you get the proper gear (beacon, shovel, probe) and have the necessary training to do so. That training often begins with AIARE 1 courses, helping you learn how to prepare for and conduct trips through the backcountry. If you want to start learning about avalanches before taking an AIARE course, there are plenty of videos and resources available on the internet. This video explores the different elevation bands that you experience in the backcountry and how they impact avalanche danger on the slopes.
The lowest elevation band is below tree line. Below tree line comes with consistent tree coverage, lighter winds, lighter snow, and warmer temperatures. Snow below tree line is often heavier, especially in the warmer months. Near tree line is the middle of the elevation bands, representing where a fair number of backcountry enthusiasts will be spending their time. There’s usually scattered tree coverage with moderate winds, moderate snow, and colder temperatures.
Above tree line is the highest elevation band. This is where there’s little to no tree coverage, often representing mountain summits or ridge lines. The wind is at its strongest, there’s more snow, and temperatures are usually the coldest. There are different types of avalanche problems that can impact all of these different elevation bands, and understanding where you are will absolutely impact your decision making throughout the day.
