Self-propelled, towing, and towed tests were conducted with several wheeled and tracked military vehicles on a variety of fine-grained and wet coarse-grained snow conditions. The 1955 tests were conducted at various sites on or adjacent to a 220-mile-long, marked trail leading from the edge out onto the ice cap the 1957 tests were all run at mile 30 on this route. Objectives of the study were to correlate vehicle performance with snow-property measurements, select an instrument that will measure snow trafficability and also meet military specifications, and distinguish snow conditions that permit a vehicle to travel from those that do not. Vehicle performance was correlated with ten methods of measuring snow strength and two physical snow properties cone index provided the best correlation.
