Please answer this question: Which island, since the mid 1960s, is the southernmost point of Iceland?
user
The southernmost point of Iceland is an island called Surtsey. Imagine it like the bottom tip of Iceland since the 1960s. It was formed from a volcanic eruption, like a mountain spitting out lava and rocks, and then it became an island in the ocean.
