I doubt, of course, that any such lake exists.

There are only a few sites in the world where permanent lakes of lava exist.

These lakes existed for a very long time, some up to 15 million years.

At the time the lake already existed as a natural feature.

There can be little doubt that the lake actually existed.

On the island small lakes exist, in which local residents bathe.

The lake does not exist today, but there is a natural spring in West Street which could have provided its source.

Just to the south of the main building, a small lake existed.

Heinitsh cleared the entire area where the lake had once existed.

This lake existed up to 11,000 years ago at the end of the most recent ice age.
