Abstract: Two test techniques were developed, one to measure the shear strength of weak layers and another to measure the tensile strength of slab layers in the snowpack. Both tests are easily applied to measurements of the naturally occurring snowpack in the starting zones with a minimum amount of disturbance of the test sample. Complete descriptions of each test including the theory, test procedures, and evaluation techniques are presented. The results of several tests conducted using both techniques are presented and discussed. The shear strength measurements compare well with previous estimates and corroborate previously discovered relationships between shear strength and normal stress. The tensile strength measurements compare well with previous uniaxial tension tests performed on similar sample sizes and snow types. As these test techniques are perfected in the future they will be able to provide specific strength data and a better understanding of snow behavior:
