2 million-pound) building exerts significant concentrated loads on the snow foundation. Considerable thought went into the design of this foundation (Berry and Braun 1999). Of principal concern was settlement, both average and differential, into the deep snowpack present at the South Pole. Unfortunately for the designers, little practical guidance could be found in the literature. Snow engineering was and remains an immature field, though it has been of keen interest to early polar explorers, to some early-1900s scientists, and to mid-1900s military researchers (Shapiro et.

There is clearly differential settlement among the columns, even within a particular wing. However, following the first year after installation, differential settlement does not seem to be increasing but remains fairly uniform. An odd feature we identified is the irregular nature of settlement during the South Pole summer (mid-November to mid-February), when measurements are taken at least monthly. Very few of the column’s data depict a smooth settlement pattern over these four or five closely spaced measurements.

There are dramatic changes in settlement rate (both speeding up and slowing down) for the dense snow pad into the “natural” firn on which it was built, and those will be the topics of future investigations. There is clearly differential settlement among the columns, even within a particular wing. However, following the first year after installation, differential settlement does not seem to be increasing but remains fairly uniform.
