Snow survey equipment

The Utah Snow Sampler, which is an adaptation of the Mt. Rose Sampler, and its scale and accessories are described. In the new sampler the throat of the cutter has a diameter of 1.4872 inches instead of the 1.5 inches, so that 1 inch of water is made to weigh 1 oz., permitting easy conversion to inches of water when ordinary commercial scare readings are used and also facilitating the calibration of special scales. The Utah Sampler uses A1-alloy tubing which is rust resistant, has an extremely smooth bore, and equals structural steel in strength with only 1/3 of its weight. The snow scale developed for the sampler is tubular and much lighter and more compact than the Mt. Rose Scale, but lacks a means for setting the index at zero. Scales of different capacity are required for snow covers of varying depths and high water content, scales of larger capacity being constructed with the spring under an initial tension. George D. Clyde described the Utah Snow Scales, Aluminum tubes. The scales, cradle, sampler and cutter are pictured.
