Did Scandinavian glaciers survive the warmer conditions of the early Holocene? Ice thickness measurements, proglacial lake sediment, and cosmogenic nuclides in bedrock alongside Riukojietna, a small low-elevation ice cap in northern Sweden, all combine to constrain a glacier advance and retreat history since 9.8 thousand years ago. Riukojietna was small but persisted through the early Holocene, illustrating that other but higher-elevation valley glaciers in the region may also have done so.
