Abstract: Old South Pole Station was built between 1956 and 1957 to support the International Geophysical Year (IGY). At the time, the buildings composing the main station complex were built on the snow surface, but the increasing depth of snow overcame the structures. In an effort to displace the deepening snow and resulting snow loads, wooden structures called “top hats” were built on top of the roofs of the original buildings. These buried buildings and additional top hat structures created dangerous subsurface voids and then further acted to weaken overlying snow layers. Therefore, we conducted ground-penetrating-radar (GPR) surveys at the Old South Pole Station site to identify buried buildings and potential hazards. The GPR survey included techniques used in crevasse detection to identify the locations and dimensions of the buildings. GPR located several top hat roofs as shallow as 14 ft below the snow grade with the roofs of the station buildings 30 ft below the surface at the time of the survey. As a result of this study, GPR located nine buildings within the main complex, which were then imploded using blasting. This report describes the methods used to identify the buried buildings and reviews the blasting operations.
