abstract
In order to acquire information about the dynamics of internal movement of a rock glacier, the three-dimensional eigenvalue technique was applied to the fabric analysis of 13 samples of clasts from a vertical section in a 15 m deep trench in this landform on Mt. Mestas, Colorado, USA. Two hypotheses were posed to explain the cyclic data: 1) three temporally, distinct, catastrophic debris flows contributed to the development of the rock glacier, and/or 2) the three groups of samples can be attributed to internal shear planes. -from Authors
