Ice shelters are temporary structures made from snow and ice, commonly used in cold environments for protection against harsh weather. They are often built by hunters or outdoor enthusiasts in snowy regions, providing a warm and safe space to rest or sleep. These shelters can take various forms, such as igloos or snow caves, and are designed to retain heat while blocking wind. The construction typically involves compacting snow to create walls and ceilings, which can insulate effectively. Ice shelters are essential for survival in extreme conditions, allowing people to stay safe and comfortable.
