Deep groundwater circulation through the High Arctic cryosphere forms Mars-like gullies

We report here the discovery of the northernmost known perennial spring, located in the polar desert of the Canadian High Arctic (average precipitation 75.5 mm/yr; average annual air temperature –19.7 °C). The high-discharge spring (~520 L/s) has also anomalously high temperatures (9.0 °C), despite...
