The map of Gurgler Ferner (1 : 10.000) was used for determining changes of volume and mass compared to earlier surveys, as a basis for a geophysical determination of ice thickness, and as a glaciological document. The cartographic evaluation emphasized the terrain surrounding the snow and ice covered areas.Gurgler Ferner covers an area of 10.7 km2 , 60 % of which are situated between 2800 and 3100 m, the altitude range of the equilibrium line. From 1969 to 1981 the glacier and its tributaries lost 25 *106 m**3 of water, equivalent to a mean lowering of the surface by 17 cm per year in good agreement with the value of Hintereisferner.
