Short summary
Glacier Echaurren Norte (ECH, 34° S) has the longest (> 35 yrs) mass-balance record in South America. A minimal model that explains 78 % of the variance in the ECH annual record identifies precipitation as the most important forcing. A regional streamflow series allows for extending the ECH annual record back to 1909 and shows a clear cumulative ice-mass loss. Similarities with documented glacier advances and other shorter mass-balance series suggest the ECH reconstruction is regionally representative.
