Avalanche Risk Slope Angle. Slab avalanches (cohesive layers of snow which can be very soft or very hard) tend to be less frequent on slopes steeper than 45 degrees, as the snow tends not to build up into thick, deep slabs. Avalanches are possible on any slope steeper than 30 degrees and occur most frequently on slopes 35 to 50 degrees. Slopes between 30 to 45 degrees are most prone to avalanches, but they can occur on slopes as gentle as 25 degrees or as steep as 60 degrees. This article shows a few methods. slope angle is a key factor for dictating whether or not the terrain can produce an avalanche. slope angle is by far the primary consideration for avalanche potential; There are some misconceptions that convex rollovers are always more dangerous and that concave slopes are safer. The direction a slope faces can significantly affect snowpack stability, with certain aspects more likely to accumulate unstable layers of snow due to wind deposition or solar radiation. You can use an inclinometer. Most slab avalanches initiate on slopes where the steepest slope angle is between 30° and 50° (about the steepness of a black or double black diamond run at a ski hill) and subsequently run into lower angled terrain. knowing the slope angle when navigating avalanche terrain is key to your safety. Slope shape plays only a minor role.
