Rock glaciers (RG) in the Swiss National Park, the first globally where in-situ measurements of surface displacement were made (1918), show a general deceleration and volume loss trend over the past century. Photogrammetric analysis reveals kinematic changes influenced by adjacent glacier hydrology. Ongoing glacier degradation will likely lead to limited future accelerations; instead, gradual secondary creep sustained by water flow from adjacent glaciers will progressively slow as permafrost degradation continues.
