Abstract

The measurements of frost depth were obtained by the use of a King soil tube and hammer. After measuring snow depth the tube was driven into the soil profile gradually. The core samples were removed and examined for ice crystals. The depth at which these crystals occurred was recorded as the frost depth. Some of the factors which have been found to affect frost penetration are snow depth, vegetal cover, atmospheric pressure, exposure, initial soil temperature, moisture content of the soil, soil type, snow density, and organic matter contained in the soil. Graphs are shown at each station and date with the depth of snow and of frost line. The type of ground cover and soil type are shown. The data collected is shown in tabular form. Open discussion comments are included from several engineers.
