I ski in the backcountry for the snow. There are less people willing to hike for their turns, therefore the snow stays untracked longer. It's also very gratifying to earn your turns. Other reasons, in Colorado, many mountains have backcountry gates, Vail, Beaver Creek, A-Basin, Steamboat, etc. It is easy to hike for an hour or less, and still be able to ski to a lift. A lot of the terrain that we ski is borderline avalanche terrain. It gets the snow, but isn't always super steep. Generally, an avalanche won't break unless you are on a 30 degree or steeper slope. The risk generally goes up as this slope gets steeper. We'll ski a lot of powder fields that are in the high twenties to low thirties, minimizing risk. If we go into steeper areas, we follow some guidelines to reduce our risk. Making sure everyone has a shovel, probe, and beacon is just a start. There are a lot of resources on the web. Check out
