Abstract
Two cases of the buckling of hard-pack snow on a hillside of constant slope are investigated. One model is based on a linear viscoelastic surface slab above a similar viscoelastic sublayer. The second model is of a viscoelastic slab resting on a rigid base. Questions resolved from the analysis of these models are the rise times for order of magnitude changes in buckling mode amplitude, the overburden conditions necessary for the formation of buckling modes, and the effect of subsurface imperfection size on buckle formation. It is suggested in field observations of avalanche-sensitive slopes that consideration of buckle mode formation be included in physical measurements.
