c. Snow
Compacted snow conditions allow one to progress on foot. Frequently crampons are required to travel efficiently over snow and ice. Crampons have 8-14 spikes and are attached to a mountaineer's boots. They are used on hard snow (neve) and ice to provide additional traction and allow very steep ascents and descents. Varieties range from lightweight aluminum models intended for walking on snow covered glaciers, to aggressive steel models intended for vertical and overhanging ice and rock. Snowshoes can be used to walk through deep snow. Skis can be used everywhere snowshoes can and also in steeper, more alpine landscapes, although it takes considerable practice to develop strong skills for difficult terrain.
