A Party assembled at the Berliner Hütte in the Zillertal (Austrian Tirol) from 2 to 9 September 1951 for the purpose of glaciological and other research. Fifty research workers and scientists took part including Professors R. Finsterwalder (Munich), C. Troll (Bonn) and H. Kinzl (Innsbruck). The main purpose of the course was the investigation of glacier recession and the many phenomena resulting therefrom. The glaciers of the Zemmgrund and the Schlegeisgrund were photogrammetrically surveyed and their exact positions mapped.Footnote *
Measurements of glacier speed, of radiation and of ablation were also made. Special attention was given to the areas which had become ice-free since 1850; new methods of mapping these were devised and tested by investigation of their gravels and lichens.
This course was a continuation of the research courses initiated by Sebastian Finsterwalder in 1913 and which have been continued at intervals since that time.
