Short summary
This study presents an age profile of the summit glacier of Weißseespitze in the Austrian Alps. The ages were obtained by combining 14C dating with the novel atom trap trace analysis for 39Ar. The data was used to constrain glacier age models. The results show that the surface ice is ~400 a old due to recent ice loss. The remaining ice continuously covers ages up to 6000 a. This work underscores the utility of 39Ar dating in glaciology, enabling precise reconstruction of age-depth relationships.
