Excursion: Terminal Moraine

Hindens rev (hind reef)

A terminal moraine is a result of a glacier in a standstill. Usually during cold periods a glacier can remain locked in the same position (because it is frozen onto the substratum, i.e. cold base) for a considerable amount of time.

During this time material is still being transported within the ice strata and deposited at the ice margin. This gives a very good measure as to what areas actually had glacial cover at a certain time.

This particular moraine is actually part of a much larger system of moraine depositions that stretches from southern Norway, all the way across Sweden and ending somewhere at the Russian arctic coast.

Interesting stuff. A moment (or more like several hundred years) frozen in time forever bearing witness of its existence. Like an epitaph for this mighty phenomena that one day will return again.
