Can you use snow as a water source in the tundra?

Collecting and Melting Snow

In the tundra, snow is abundant but often dispersed across the landscape. A technique called “snow block” collection is effective for gathering a large quantity of snow. To create a snow block, dig a shallow pit and place a tarp or plastic sheet in the bottom. Fill the pit with snow and cover it with the tarp. Pack the snow by stomping on the tarp or using a shovel to compact it. A compacted snow block can weigh up to 200 pounds and melt into 1-2 gallons of water.

Purifying Water in the Tundra

Purifying water from the melted snow is crucial to avoid waterborne illnesses. In the tundra, using a solar still is an effective method for purification. Create a solar still by digging a shallow pit and placing a container in the center. Add a small amount of water to the container and cover it with a clear plastic sheet. Place a rock or weight in the center of the plastic sheet to create a depression. As the sun heats the plastic sheet, water will evaporate and condense on the underside of the plastic, dripping into the container below. This method can produce up to 1 liter of purified water per hour.

Finding Shelter from Wind Exposure

In the tundra, wind exposure can make finding a suitable snow source challenging. To protect yourself from the wind, create a snow shelter or a windbreak. Dig a shallow pit and cover it with a tarp or snow blocks to create a windbreak. Alternatively, follow caribou tracks to find areas with more sheltered snow sources. Caribou often follow the same routes through the tundra, which can lead you to areas with more abundant and accessible snow. In these areas, look for lichen and berries, which can indicate the presence of other water sources.
