The great terminal moraine of the glacial epoch crosses the N.E.
Their origin is attributed by some to the moraine formation of former glaciers.
The lakes and water-basins may be classified in four groups, each with its own peculiar scenery and distinct mode of origin - (I) glen lakes, (2) rock-tarns, (3) moraine-tarns, (4) lakes of the plains.
Still, the reindeer frequents it for its lichens, and on the drier slopes of the moraine deposits there occur four species of lemming, hunted by the Arctic fox (Vulpes lagopus).
The typical bottom moraine, with erratics from Finland, extends all over the country.
The locality of least annual thermometric range is Lake Moraine (10,268 ft.
It was entirely covered with the bottom moraine of the great ice-sheet of the Glacial Epoch, resting upon Silurian sandstones and limestones.
Swedish geologists distinguish between bottengrus (bottom gravel, bottom moraine) and ordinary krossgrus (terminal and side moraine).

There is evidence also that glacial moraine formations from time to time may have largely affected the catchment area of these tributary streams. It would be as rash to assert that from Lake Victoria no waters could ever have issued with an eastward flow as it would be to state that 'from Chakmaktin none ever flow westwards.
In the north-western counties, where the glaciers continued longest to descend to the sea-level, lakes retained by moraine-barriers may be found very little above the sea.
Hence their bottoms are generally ice-worn or strewn over with moraine stuff.
