Snow Conditions
Snow was not uniform substance—it varied by temperature, humidity, age, wind exposure, underlying terrain. Fresh powder was light, deep, difficult to travel through. Wind-packed snow was dense, supported weight, allowed faster travel. Wet spring snow was heavy, stuck to equipment, exhausted travelers. Each type demanded different techniques and equipment.
Understanding snow conditions required observation and experience. Touching snow revealed temperature and moisture content. Observing surface appearance indicated whether it was loose or packed. Testing with probing stick showed depth and whether hard layers existed beneath surface. The skilled winter traveler read snow constantly, adjusting technique and route based on conditions encountered.
Temperature Effects
Cold temperatures created hard, crystalline snow that supported weight—ideal for travel. Warmer temperatures created softer snow that collapsed under weight, making progress exhausting. Temperature also affected equipment—ski bases behaved differently in cold versus warm conditions, snowshoe webbing became brittle in extreme cold, metal tools became dangerously cold to touch without protection.
Daily temperature cycles created crusts—snow melting slightly during day, refreezing at night into hard surface that might support human weight in morning but break through by afternoon. The experienced traveler used these crusts when possible, timing travel to conditions that aided rather than hindered progress.
