Winter satellite image of the Holger Danskes Briller terminal moraine in Kjove Land, East Greenland. This is referred to as a delta moraine, because it is associated on its outer edge with a fluvioglacial terrace at 101m asl. The lake inside the moraine is to the left of the ridge.
The largest terminal moraine in Vestfirdir, NW Iceland -- in the glacial trough of Kaldalon. Summer satellite image. The up-glacier side is to the right. Sandur and tidal flats to the left, with gravel track and landing strip.
It is tempting to correlate the big terminal moraine that blocks the eastern end of the Holger Danskes Briller trough in Kjove Land (East Greenland) with the big terminal moraine in Kaldalon which is labelled as Jokulgardur. They are both significant landscape features, and both represent the stillstands of significant glaciers within glacial outlet troughs. Well East Greenland is not so far away from NW Iceland, and the two regions must have experienced broadly similar climatic shifts following the LGM glacial episode. There are differences, of course; the glaciers associated with Drangajokull are of course much smaller than those associated with the ice cap in East Greenland, and so might be expected to react more quickly to climatic oscillations. The histories of relative sea level are very different on both sides of the Denmark Strait. But there was surging glacier behaviour in East Greenland just as there was in Vestfirdir..........
The Milne Land stage in Greenland is the approximate geological time equivalent of the Búði stage in Iceland. Both represent significant glacial events that occurred during the Late-Glacial period, specifically correlated with the Younger Dryas climatic "event".
Milne Land stage (Greenland): This stage refers to a period of significant glacier advance or stillstand in East Greenland, marked by prominent moraine systems. It is primarily dated to the Younger Dryas chronozone, approximately 12,800 to 11,500 years ago (or slightly before this time, in the Pre-Boreal).
Búði stage (Iceland): This stage also represents a major readvance of the ice sheet in Iceland. It is correlated with the Younger Dryas cold period, occurring around 11,000 to 10,000 years BP.
Both stages reflect regional climatic shifts near the end of the last ice age, making them correlative in geological time within the North Atlantic region.
