Quick Answer
Elevation and terrain play crucial roles in shelter choice by influencing wind, snow, and accessibility, with higher elevations often experiencing harsher conditions and denser snow cover, while steeper terrain may require more labor-intensive shelter construction.
Choosing a Shelter Site
When selecting a shelter site, it’s essential to consider the elevation and terrain. In cold winter conditions, it’s best to find a location with lower to moderate elevation, ideally below 2,000 feet, to minimize the risk of avalanches and deep snow drifts. A site with a relatively flat slope of 10-20 degrees is ideal for building a snow shelter, allowing for easier excavation and more stability.
Building a Snow Shelter
When building a snow shelter, consider the wind direction to minimize exposure to harsh winds. A site with natural protection, such as a group of trees or a boulder field, can also help reduce wind impact. For a snow trench shelter, aim to dig a trench 6-8 feet long and 2-3 feet wide, with a slope of about 30 degrees to prevent water from accumulating. This design will provide a relatively dry and protected space.
Final Considerations
When evaluating a shelter site, also consider accessibility and visibility. A site with clear visibility to surrounding terrain can help you spot potential hazards, such as avalanches or wildlife. Additionally, choose a location with a reliable water source, such as a stream or spring, to minimize the risk of dehydration. By carefully selecting a shelter site based on elevation and terrain, you can increase your chances of survival in cold winter conditions.
