Abstract: Summary: Data previously obtained in a program of instrumentation and observation to appraise the performance of radar station N-34 built at an altitude of about 7000 ft in the dry-snow zone of the Greenland Ice Cap are condenser and presented. N-34 consisted of prefabricated buildings erected inside tubular corrugated-steel shells and the whole complex was interconnected with a closed network of steel tubes. The snow cover accumulation on the abandoned station, from 1957 to 1963, of more than 20 ft is still being restrained by the structural shells. Observations of long-term effects on this unique structure are utilized to analyze new and existing data in evaluating design concepts. Structural deformation, differential settlement, and heat loss are discussed, and some remarks relevant to future design are made.
