Statistical analyses were made of the snow course measurements on a 714‐acre forested subalpine watershed in central Colorado where melt rarely occurs during the winter snow accumulation season. The following guidelines were developed for sampling mountain snowpacks on an areal basis: (1) sampling zones should be stratified by elevation, the sampling in each zone being proportional, and (2) sampling points should be widely spaced over each zone, two duplicate measurements at most being made at a location.
