WebJan 20, 2024 · The Rutschblock test measures primarily surface layer deformation, but if deformation penetrates deep enough with enough deformation energy to fail snow in a weak layer it indicates local instability. A great advantage of the test is that it includes provision for application of dynamic loads which can partially replicate skier loading.
