Short summary
We propose a sub-seasonal timescale based on pollen analyses for a Mt. Ortles firn core. The method can be applied to all types of glaciers, provided the proximity of the pollen source and a negligible time lag between pollen production and its deposition on the glacier. By combining pollen dating with a mass balance model we found evidence that pollen grains are resilient to downward transport by percolating water and that pollen shows a high potential for inferring past climatic conditions.
