Abstract

A Mount Rose type sampler with a cutter of inside diameter 1.485 inches was compared in field tests with a sampler having a cutter with inside diameter of 2.787 inches. The results of 32 samples with each set gave a coefficient of variation of 7.82% for the Mt. Rose sampler and 9.24% for the larger sampler. Additional 15 measurements using the gram scales gave lower values but similar variations. The Mt. Rose type of snow sampler proved more practical and as accurate as the larger sampler, under the conditions of the tests. Comparative data are exhibited in tables.
