Snow movement in polar areas creates logistical problems for at-grade, or surface, camps in areas of positive snow accumulation. Snow drift studies, which were made over a 4-year period around a single unprotected building and around a cluster of buildings in an area of positive snow accumulation on the Ross Ice Shelf near McMurdo Station, Antarctica, showed that at-grade camps will eventually become covered with drifting snow. Drift control measures, however, can be used to increase the usefulness of such camps. The drift control measures developed in this report, which cover proper building orientation and camp layout with respect to the major storm winds, can be used to improve access and reduce maintenance for at-grade camps in areas of drifting snow. In addition, mobile foundations should be used for all buildings to facilitate camp moves when snowdrift becomes excessive, and small camps should be built on elevated snow platforms to extend their useful life.
