Using snow for water storage in winter camping?

Choosing the Right Snow

When selecting snow for water storage, look for areas with minimal human interaction, such as remote slopes or ridges, to reduce contamination risk. Avoid areas near animal habitats, roads, or industrial sites. Opt for snow that is at least 6 inches thick and has a temperature of 14°F (-10°C) or lower to minimize the risk of microbial growth.

Melting Snow for Drinking Water

To melt snow for drinking water, use a portable solar still or a simple DIY setup consisting of a black plastic sheet, a container, and a clear plastic sheet. Place the black plastic sheet on the snow, weigh it down with rocks, and cover it with the clear plastic sheet. As the sun heats the black plastic, it will melt the snow, and the clear plastic sheet will channel the water into the container. Aim for a melting rate of 1-2 gallons per hour, depending on the sun’s intensity and the snow’s temperature.
