A snow cave is a shelter made from compacted snow, often created by digging into a snowbank or using a shovel to carve out a space. These structures can provide protection from harsh weather conditions, such as wind and cold temperatures, making them useful for winter camping or survival situations. Snow caves are typically insulated, as the snow acts as an effective barrier against the cold. They can be found in snowy regions, especially in areas like the Alps or Rocky Mountains, where winter sports enthusiasts and adventurers may seek refuge during their outdoor activities.
