Short summary
We investigated the internal structure of two alpine rock glaciers to derive information on their development. Through a 3-D mapping of the electrical resistivity distribution of the subsurface, we could detect variations of ice content and delimit frozen and unfrozen structures. Our study shows that the development of the investigated rock glaciers is influenced by not only creep processes and remnant ice from past glaciations but also recently buried ice patches and refreezing meltwater.
