Abstract
This study is aimed to evaluate a reasonable value of snow load for the purpose of designing buildings from the data of survey. The relationship between average density and depth of snow cover is discussed. As the results, the followings are found. (1) The average density of snow cover is within the range between the minimum derived from the distribution of density of snow layer in case of heavy snow fall and the maximum from the behavior of snow cover in melting process. (2) The maximum weight of snow cover is given by the maximum curve of the average density.
