Abstract

Three weaknesses were observed in a duraluminum snow sampler during a field test. Teeth from the cutter bit broke when the sampler met a 4 inch crust of ice down in the snowpack. The sleeves on the end of the sections of the sampler turned in attempting to drive the sampler through the ice crust. The spanner wrenches failed to hold when attempt was made to unscrew the sections after sampling. Changes in the duraluminum snow sampler to remedy these defects are recommended.
