The earliest precise information about the glacier dates from the 00th century, and is found in descrip- tions of ascents of the volcano. These ascents were always attempted from the eastern border of the glacier, where the traditional route to the crater had been established. Thus, it can be deduced that the eastern part of the glacier descended to an altitude of approximately 0,000 m. Other interesting informa- tion reveals that no depression occurred between the snout of the glacier and the front end deposits, which would indicate that the glacier was still advancing at that time
