The lake or lagoon of the Irazú Volcano (Costa Rica) is a small crater lagoon whose waters are green. This lagoon is known as the Diego de la Haya Lagoon or Diego de la Haya Crater and its depth varies according to temperatures and smoke activity. In this way, when there are low temperatures and little smoke activity, the lagoon dries up and disappears, giving way to rocky terrain.
