WALTER WILCOX/WHYTE MUSEUM OF THE CANADIAN ROCKIES (TOP) - THEO MLYNOWSKI VIA GLACIERCHANGE.ORG . Co-author Atle Nesje, a glaciologist at the University of Bergen, says that thousands of years ago, warm summers probably exposed older artifacts, which were carried to the edge of the ice patch by streams of meltwater before freezing again. Because old arrows might be washed down by meltwater and then re-freeze, the spot where they were found could be a long way from where they originally landed. Neil Glacial lakes, which are often dammed by ice or glacial sediment called a moraine, are not stable like the mountain lakes most are used to seeing. Further, the latter effect may be more effective, given the steepness of glacier-fed rivers, which can enhance their dynamics. It’s a lot of change,” says Nesje. The weight of ice pressing down on lower layers might have caused them to shift, carrying their frozen contents with them. About 20 when he died, he … Specifically, the Greenland and Antarctic ice sheets are the largest contributors of global sea level rise.

Lakes have formed from melting glaciers and are dammed by unstable moraines, which are soil and rock debris that was left behind by moving glaciers. Unlike glaciers, which are essentially slow-moving frozen rivers, ice patches are fixed deposits of snow and ice that may grow and shrink over time. They can be quite unstable and are capable of bursting their banks or dams, causing massive floods downstream. Sea levels are projected to rise as this process continues, affecting millions of people living along coastlines and in island nations worldwide.

Archaeologists in Norway have discovered dozens of arrows—some dating back 6,000 years—melting out of a 60-acre ice patch in the county’s high mountains.
