Mechanized snow surveys in Montana

A Tucker Sno-Cat, a power-driven over-snow vehicle, and a two man crew of trained snow surveyors were used to measure 24 snow courses extending a distance of 300 miles. The 1948 model Sno-Cat, 4-door sedan, was powered by a 95 HP Plymouth engine, and had a 3 speed transmission. The unit was equipped with sleeping bags, tent, stove, and emergency supplies for 2 men. A Dodge Power Wagon with a special bed on the chassis was used to transport the Sno-Cat in the valleys below the snow line. The Sno-Cat traveled 331 miles between February 12 and February 29, 1948 over light sandy snow up to elevations of 9000 feet. The Sno-Cat averaged 5.1 Mi./gal. Gasoline and the repair costs were $10.70. The Dodge Power Wagon averaged 8 Mi./gal. Gasoline over roads considerably snow-blocked. Snow-Catting was difficult where snow lacked cohesion. Wider and longer front skis are recommended to increase the bearing surface.Discussion by Fred Paget.
