The answer is the Danakil Depression in northeastern Ethiopia. It is located at an altitude of 125 meters (410 feet) below sea level and contains a large salt lake known as Lake Assal. It's estimated that this salt field covers over 1,000 square kilometers (386 square miles). The area is home to a variety of wildlife, including monkeys, camels, flamingos and small mammals. The salt flats are also mined for their large deposits of potassium chloride, magnesium sulphate and sodium chloride. This area is incredibly hot with temperatures reaching up to 50 degrees Celsius (122 degrees Fahrenheit). Despite its harsh conditions many people still come here to admire the stunning landscapes of this incredible natural wonder. The Danakil Depression is truly a sight to behold!
