Pick up your phone and call the avalanche hotline to find out what the danger in your area is and in the area you will be riding. You should do this every time before you go out for a ride. Most all areas have a number you can call for this information. While out on your ride, pay attention and be aware of the conditions around you. These are just a couple of the questions you need to ask yourself.
Avalanches can occur on long or short slopes.
A 38-degree angle is most common for avalanches. You can purchase an inexpensive compass with an inclinometer built into it for measuring slope angles. Practice safe riding techniques on your sled. Cross high-risk areas one at a time. That way you have lots of eyes on you should the unthinkable occur, as well as there only being one victim.
