On a long or steep slope you can descend at a much slower rate by traversing with your skis parallel and at an angle diagonally across the slope. The angle you chose will determine the speed. If you are carrying a heavy pack, or are not confident on a steep slope, a series of traverses is the safest option. A relaxed stance with the upper body leaning slightly outward and down the fall line will help you to roll your knees and ankles inward for edging control. Usually the uphill ski should be ahead of the downhill one. The depth and type of snow will determine how you traverse. If the snow is deep and soft, little or no edging of the skis will be required, but if steep and icy, precise control of the edges is necessary.
