MARC recordSnowpack characteristics associated with avalanche accidents / James Bruce Jamieson, C.D. Johnston.
| Title: | Snowpack characteristics associated with avalanche accidents / James Bruce Jamieson, C.D. Johnston. |
| Author(s): | Jamieson, James Bruce. Johnston, C. D. |
| Date: | 1992. |
| In: | Canadian Geotechnical Journal. (1992.), Vol. 29(5) (1992) |
| Abstract: | Most fatal avalanche accidents in Canada between 1972 and 1991 involved dry snow slabs and were triggered by people. Slab thicknesses averaged 0.86 m and over half included snow deposited before most recent storm. Surface hoar and faceted grains were often reported in weak layers believed to have released overlying slabs. Experts and non-experts had difficulty in recognizing or evaluating instablities involving these two features, suggesting that present field tests and forecasting techniques may be unsatisfactory for assessing them. |
