Short summary
Pseudo-relict rock glaciers look relict but contain patches of permafrost. They are poorly known in terms of permafrost content, spatial distribution and frequency. Here we use spring-water temperature for a preliminary estimate of the permafrost presence in rock glaciers of a 795 km2 catchment in the Italian Alps. The results show that ~50 % of rock glaciers classified as relict might be pseudo-relict and might contain ~20 % of the ice stored in the rock glaciers in the study area.
