Abstract: Abstract: Lightweight portable structures have been installed in excavations in snow for the purpose of procuring, over a long period of time, stress and-strain behavior data of massive snow such as exists over an extensive area of Greenland. The trench-shoring-type structures will develop lateral pressures, and column-type structures supporting trench covers will develop increasing loads from snow accumulation, both of which are to be measured periodically with electrical strain-gage-type pressure cells. Supplementary structures exhibiting visible responses to snow accumulation and consolidation with time, including lightweight metal arches and a shelter composed of snow-block walls with a prefabricated metal roof structure, were also installed and observed. Initial observations include description of the excavation procedure and, briefly, load characteristics.
