Title of Research Project:

THE EFFECTS OF CANOPY COVER AND SHADING ON SURFACE HOAR SIZES IN SMALL FORESTED MEADOW OPENINGS

Project Summary:

Understanding variations in slope scale snowpack properties influences stability assessments at the slope and regional scale.  Previous studies have shown that surface hoar, a prominent weak layer type, can vary in initial crystal size and height across small, seemingly homogenous meadows and sparsely forested areas on northerly aspects. The differences in size have generally been attributed to the radiation balance, which is difficult to estimate in the field.  This study aims to further investigate the effect of canopy cover and shading on the growth of surface hoar in small forested meadow openings just after initial growth and prior to burial.  Two small (approx. 30m x 50m) study plots located in southwest Montana were selected.  The study plots, one northern and one southern aspect, are mostly planar 10° meadows surrounded by heavy tree cover.  Over the course of 2 winters samples will be collected at these study plots.  Estimations of canopy cover and shading will be conducted using hemispherical fisheye photography.  These estimations will then be used to compare these factors to the sizes of surface hoar in the meadows.
