It is known from what are interpreted as lake deposits.

Important lake deposits, predominantly clay, were thus laid down in the Monongahela River basin.

The presence of Altenglanerpeton in a lake deposit suggests that it was aquatic.

The crater is of great interest to scientists because it has some of the best-exposed lake deposits.

Recent geological investigations indicate that the oldest lake deposits has been radiometrically dated as old as 125 thousand years.

This situation prevailed for several hundred years as evidenced by lake deposits beneath and around Llangorse Lake.

These varved lake deposits were later used by European settlers for brick-making.
