Book Description
Observations were made at 19 sites in and around the Fort Greely Military Reservation in Alaska during the winter of 1966-67 to obtain data on the depth and physical properties of the snow cover. Snowfall in 1966-67 totaled 245 cm, which was more than 2-1/2 times the seasonal normal. Maximum snow depths of 80 to 100 cm were observed in a major portion of the reservation. Measurements at nine sites showed that the snow density at Fort Greely was generally light; e.g., the average density in the forest did not exceed 0.24 g/cu cm. However, exceptions such as at Jarvis Creek, where the density averaged 0.33 g/cu cm, could be expected. On the average, less snow falls at Fort Greely than at other interior Alaskan locations; but the average density of the snow cover at all interior Alaska sites is quite light. Relationships between snow-cover properties and climate were tested using data collected at Fort Greely. The results substantiated the relationships between (1) snow hardness and snow density measurements and (2) average snow densities with average windspeed and air temperatures. Snow temperature measurements at Fort Greely showed that the snow in the forest was colder than at exposed sites, primarily because the average air temperature within the forest canopy was lower than that in the open area.

Book Description
Present military concepts call for highly mobile units capable of rapid dispersal and efficient movement across country where no roads exist, and many current civilian engineering tasks require movement of men and materials long distances over roadless terrain. Oversnow transport is a particular aspect of the general problem of cross-country mobility, but the characteristics of snow-covered regions are such that special techniques and equipment are required for efficient operation. In order to fully understand the action of vehicles in snow and to formulate sound design criteria, it is necessary to develop a theory which permits quantitative analysis of trafficability problems. For practical purposes, vehicle evaluation is at present made from the results of relatively simple field tests which give drawbar pull as their main indicator. The best practical evaluations are made by observing the operational capabilities of vehicles in various types of snow.
