So it is a depression in the ground from all the ice and this is a big deal?
“So it is a depression in the ground from all the ice and this is a big deal?”
Oddly yes from a geologic standpoint but of no importance otherwise. It is simply a geologic curiosity that I find interesting. I myself think it is much like our great lakes that were gouged out by glaciers and now are huge lakes.
If such happened in the past prior to our last ice age it makes perfect sense. Glaciers carved out these lakes in a past ice age and the glaciers melted as always happens. These became great lakes in Greenland. Then the last Ice Age happened (Oddly we are still in an ice age but that is just by definition of geology) and thus those great lakes in Greenland are now buried under a couple of miles of ice.
