Short summary
We presented a geophysical study of one intact and one relict rock glacier in semi-arid Chile. The interpretation of the collected data through different methods identifies geophysical signature differences between the two rock glaciers and characterizes their subsurface structure and composition. This is of great importance because of rock glaciers' relevant role in freshwater production, transfer and storage, especially in this area of increasing human pressure and high rainfall variability.
