Recursive islands and lakes

Island or lake that is itself within an island or lake

A recursive island or lake, also known as a nested island or lake, is an island or a lake that lies within a lake or an island.[1] For the purposes of defining recursion, small continental land masses such as Madagascar and New Zealand count as islands, while large continental land masses do not. Islands found within lakes in these countries are often recursive islands because the lake itself is located on an island.

Vulcan Point became a peninsula.[citation needed]
