Short summary
We used two lake sediment records at different elevations and landscape evidence to find that a southern Greenland outlet glacier advanced ~ 3700 years ago and then retreated ~ 1600 years ago. This retreat is unlike other nearby outlet glaciers, possibly because of the complex local ice structure or greater sensitivity to snowfall. We also find that the advanced ice surface had an elevation of ~ 670 m a.s.l. (~ 250 m higher than today) from ~ 3700 to 1600 years ago.
