Dallol is a cinder cone volcano in the Danakil Depression in northern Ethiopia. It features strange volcanic landscapes and is one of the hottest places on Earth. The elliptical Dallol rises 60 m above the salt plain but is nonetheless below sea level. Its summit crater is about 100 m in diameter. Mud, salt, iron stains, halophile algae, and hot spring activity produce a colorful but dangerous landscape in the Dallol craters. Shown are sulfur pools.
