What are common mistakes when setting up a space blanket shelter?

Improper Anchoring

Improper anchoring is one of the most common mistakes when setting up a space blanket shelter. This occurs when the blanket is not properly secured to the ground using rocks, sticks, or other available materials. Aim to create at least two anchor points per corner of the blanket, spaced at least 12 inches apart. This will help distribute the force of wind and prevent the blanket from being blown away. For added stability, create a perimeter of anchor points around the edges of the blanket, spaced at 6-8 inches apart.

Single-Layer Construction

Another common mistake is using the space blanket as a single-layer structure. This is often done by folding the corners of the blanket under to create a basic rectangular shape. However, this design provides little to no protection from wind, rain, or snow. To improve the structure, create a “lean-to” design by anchoring one end of the blanket to a tree or rock, and then laying the remaining portion of the blanket out in a slope. This will allow you to collect rain and snow on the upper portion of the blanket, while keeping the lower portion dry.

Slope and Drainage

Failing to create a slope for water runoff is another critical mistake when setting up a space blanket shelter. A slope of at least 10-15 degrees is necessary to prevent water from pooling on the surface of the blanket. To create this slope, place a series of rocks or sticks along the length of the blanket, angling them outward to create a gentle incline. This will allow water to run off the surface of the blanket, rather than collecting in a pool and potentially causing the structure to collapse.
