What's in the photo? A crater lake and frozen lava flows in the mountain's caldera.When was it taken? April 17, 2022.
Mount Nemrut, which was named after the biblical figure King Nimrod, stands 9,672 feet tall at the intersection between the Arabian and Eurasian tectonic plates. The dormant stratovolcano last had a major eruption in 1650, according to NASA's Earth Observatory. The snow coverage also accentuates folds in the lava flows known as pressure ridges, which were formed by the flowing and cooling of molten rock. These ridges vary widely in size and thickness due to differences in the viscosity of the lava across different eruptions, according to the Earth Observatory.—Trio of multicolor lakes look otherworldly in Africa's Great Rift ValleyNemrut's crater lake has a maximum depth of around 577 feet and covers similar lava flows from past eruptions.
