What is a key characteristic of a snow bollard?

The key characteristic of a snow bollard is that it is typically a teardrop-shaped mound of snow. This shape is crucial because it helps to provide a larger surface area at the base, which enhances the stability of the bollard when it is subjected to loads. The design allows for a better load distribution, reducing the risk of collapse under tension. The teardrop shape also aids in preventing the snow from melting or being compacted too easily, thereby maintaining its strength and effectiveness as an anchor point in rescue scenarios.

This understanding of a snow bollard’s function and structure assists rescuers in assessing the effectiveness of snow as a medium for creating anchors in winter rescue operations.
