Lava Lakes; Where to Find Them & How to Spot Ancient Lava Lakes

Описание: Despite being widely associated with active volcanoes, lava lakes are in fact quite rare. Yet, a few of them still do exist, and can be quite large. Today's video discusses each of these lava lakes, shows a size comparison, and some interesting facts relating to how they form. It also discusses one method of spotting "fossil" ancient lava lakes in old igneous rock outcroppings.
