Short summary
In the scientific literature, “protalus ramparts” can designate both a nivo-gravitational landform (also called “pronival ramparts”) and a permafrost-related landform. Thanks to a selection of eight major diagnostic criteria defined from observations carried out in the Swiss Alps, it was highlighted that the structure, ice content and creep dynamics of protalus ramparts are the same as many rock glaciers. Protalus rampart were therefore defined simply as a (small) active talus rock glacier.
