Main publication details
MARC recordNeuer Schneedeckentest / Jürg Schweizer.
| Title: | Neuer Schneedeckentest / Jürg Schweizer. |
| Translated title: | New snow cover test. |
| Author(s): | Schweizer, Jürg. |
| Date: | 2007. |
| Language: | German. |
| In: | Alpen : Zeitschrift des Schweizer Alpen-Clubs. (2007.), Vol. 1 (2007) |
| Abstract: | Describes novel six-point test for avalanche risk, based on properties of snowpack layers and contrasts between them, and derived from stratigraphic comparison of unstable snow covers (close to avalanche fracture lines) and more stable ones. Six points are: layer weakness (yielding to firm fist), crystal size (>1 mm), and crystal shape (angular, rather than rounded); contrasts between adjacent layers in hardness and crystal size; and weak layer <1 m below surface. Describes interpretation of points score, and complementary compression test on 30 cm-square snow column, emphasizing characteristics of failure rather than force required. Discusses representativeness of single site tests. Photos illustrate test and behaviour of unstable snow cover. |
