Measurements were taken over a 8–12 year period at regular intervals and the results now provide information on the variability of displacements. In the upper zone a recent slowing of movement coincides with negative mass balance of local glaciers. Discussion focuses on the variations in velocity of the rock glaciers over the short time‐scale.enGeologyRock glacierGlacierGeomorphologyPermafrostGlacier mass balancePeriod (music)Physical geographyarticle
