The h is the height of the pile of powder, and the d is the diameter. Using a scientific calculator, multiply the height by two and divide this value by the diameter. Then, hit the inverse tan key or tan 1, and the answer is calculated. This will give you the angle of repose. In snowsports, 38 degrees is the slope angle when it starts to be extra exciting for skiers and snowboarders to enjoy. Various factors, including water moisture, temperatures, and wind, determine if the snow will adhere to a slope. For instance, wet maritime snow will stick to near-vertical faces, making it possible to ski slopes exceeding 50 degrees. But skiing beyond the angle of repose adds danger if you’re skiing in the backcountry.
