Danakil Depression is one of the hottest and most inhospitable places on Earth
Numerous sulfur springs, volcanoes, geysers, acidic pools, vast salt pans, and colorful mineral-laden lakes dot the area.
Volcanic activity heats spring water, bringing sulfur and iron to the surface, leaving behind yellow, green, and orange deposits.
For centuries, locals have been trekking in with camel caravans to mine the salt by hand.
