While ascending and descending on snow, while you will follow most of the same principles as you do while walking on trails, you will need to make a few adjustments.
1. Body Position and Movement
ASCENDING
Lean forward as you would while climbing a steep trail. Focus sharply on keeping your weight over your toes and your heels raised. This is of more importance while walking on hard snow - you will feel yourself slip immediately if your heels touch the ground.
DESCENDING
While descending, lean slightly backwards and with each step, make a backward kicking motion and strike the ground with your heels first and toes raised.
2. Points of Contact
Using a pair of trekking poles can greatly aid balance while walking on snow. Focus on maintaining three points of contact with the ground at all times - with two poles and two legs. This tripod position is very stable and will prevent most potential falls.
3. Gradient Adjustment
On steep, hard snow trails, it becomes increasingly difficult to walk without traction devices like microspikes or crampons. As the gradient becomes steep and sustained, you can use the zig zag traverse for both the ascent and descent.
- With the inside (upslope) foot, hit the slope with the outer edge of the boot.
- With the outside (downslope) foot, hit the slope with the inner edge of the boot.
- Shorten the pole on your upslope (towards the mountain) side.
- Elongate the pole on your downslope (away from the mountain/towards the valley) side.
