Snow Blindness

The reflection of the sun's ultraviolet rays off a snow-covered area causes this condition. The symptoms of snow blindness are a sensation of grit in the eyes, pain in and over the eyes that increases with eyeball movement, red and teary eyes, and a headache that intensifies with continued exposure to light. Prolonged exposure to these rays can result in permanent eye damage. To treat snow blindness, bandage your eyes until the symptoms disappear.

You can prevent snow blindness by wearing sunglasses. If you don't have sunglasses, improvise. Cut slits in a piece of cardboard, thin wood, tree bark, or other available material. Putting soot under your eyes will help reduce shine and glare.

Fire

Dried moss, grass, and scrub willow are other materials you can use for fuel. These are usually plentiful near streams in tundras (open, treeless plains). By bundling or twisting grasses or other scrub vegetation to form a large, solid mass, you will have a slower burning, more productive fuel.

Warm Clothing

Dress in layers and avoid cotton. Wool or synthetics are warm even when wet, but when cotton gets wet (even from sweat), it effectively conducts heat away from the body. Wear a waterproof outer layer. If you find you are beginning to sweat, remove a layer of clothing or vent it. It is common for a person carrying a heavy load or doing heavy work (such as with an ax or shovel) to sweat even on a very cold day. Keep adjusting your layers until you quit sweating, as you do not want to be wet. When the exertion comes to an end, sweat-soaked clothing will quickly chill you.

Travel

Travelling in the snow is in many ways easier than travelling over solid ground if you have the right equipment. Snow shoes will keep you from sinking into the snow making it far easier to walk. Skis will speed you along even faster. Load your equipment on a sled and pull it along behind you. In this way you can carry far more equipment (or small children) than you could with a backpack.
