Quick Answer
CARRYING MELTED SNOW DURING A TREK IS NOT PRACTICAL DUE TO WEIGHT, VOLUME, AND HYGIENE CONCERNS. IT'S MORE EFFICIENT TO HARVEST AND STORE SNOW FOR LATER USE. SNOW CAN BE A RELIABLE WATER SOURCE WITH PROPER COLLECTION AND STORAGE.
Water Collection Strategies
When traversing through snowy terrain, it’s essential to collect snow in a way that minimizes weight and maximizes water yield. Use a collapsible snow scoop or a lightweight shovel to gather snow. For every 1 liter of snow, you can expect to collect approximately 0.8-1 kg of snow, depending on the temperature and moisture content.
Safe Snow Storage
To prevent contamination and maintain the quality of the collected snow, store it in a clean, airtight container, such as a plastic bag or a collapsible water bottle. Store the container in a shaded area or in a spot that is protected from direct sunlight. Aim to store the snow at a temperature range of 0-5°C (32-41°F) to prevent melting and bacterial growth.
Snow-to-Water Ratio and Melting
When melting snow for drinking water, it’s essential to consider the snow-to-water ratio. A general rule of thumb is to use 1 part snow to 1 part water (1:1 ratio). This will help prevent over-melting and ensure a safe drinking water supply. To melt snow efficiently, use a portable stove or a solar still, and monitor the temperature to prevent bacterial growth and waterborne illnesses.
