Abstract

Terrestrial evidence of ice-sheet meltwater events during the last deglaciation are exceptionally rare. However, they are a valuable complement to marine records that suggest immense ice-sheet meltwater pulses discharging into the Northeast Pacific, termed Siku events. Here we describe and date a terrestrial Cordilleran Ice Sheet meltwater archive in a karstified glacial outwash plain during the early last deglaciation, showing semi-continuous meltwater events between about 20,000 and 17,000 years ago.
