Short summary

We studied an ice-cored rock glacier in Taylor Valley, Antarctica, coupling ground-penetrating radar analyses with stable isotope and major ion geochemistry of (a) surface ponds and (b) buried clean ice. These analyses indicate that the rock glacier ice is fed by a nearby alpine glacier, recording multiple Holocene to late Pleistocene glacial advances. We demonstrate the potential to use rock glaciers and buried ice, common throughout Antarctica, to map previous glacial extents.
