During my PhD thesis I performed a lot of field work on Colle Gnifetti, the highest accumulation basin (4500 m) of the Gorner/Grenzgletscher system of glaciers.

The Colle Gnifetti project of VAW / ETHZ aimed at understanding the rheology of cold firn, and to investigate the thermal structure of a small, high-alpine glacier.
