On an approximately20 m deep firn pit in the accumulation area of an Alpine glacier, deformationmeasurernents have been carriedout over a perlod of 11 years.Evaluation of the data was performed by applicationof a Newtonian model, determining the shear-and bulk viscosity as weIl as by introductionof a non-linearconstitutiveequation for temperatefirn.For the transition for firn into glacier ice, Glen's Flow Law for incompressible ice results.
