Introduction: During the 1959 and 1960 construction seasons, the U. S. Army Polar Research and Development Center cut into the snow of the Greenland Ice Cap a system of interconnected trenches designed to house complete year-round living facilities for 150 men. Trenches 1, 5, 6, 7, and 19 at Camp Century were completed and most of the facilities installed in the summer of 1959. The remaining trenches and facilities, including the nuclear reactor power plant, were operational by September 1960. The camp was occupied throughout the winter of 1960-1961 at which time the operational problems of water supply, waste disposal, trench closure and radiation protection were studied in detail. USA CRREL and other agencies at Century were engaged in research projects both in camp and on the surface of the ice cap during the winter. USA CRREL, Project 13, established preliminary installations for movement measurement. In permanent snow fields, undersnow cavities, such as the trenches of Camp Century, sustain a continuous closure because of the natural consolidation of snow. Observations and study of this process and the mechanics of snow, however, indicate that useful under snow cavities can be constructed and maintained for significant periods of time. The initial measurement of a typical trench cross section was made in August 1959 at Trench 19. Since that time, 18 additional cross section measurement stations and 29 movement recording Helipots have been installed, a camp bench mark system has been established, and a number of other snow deformation studies initiated. The results to date (May 1962) are presented in the following pages. The principal purpose of these studies is to define more clearly the term, "useful life" of such installations and to establish design criteria for future construction.
