Makhtesh Ramon, a cirque measuring 40 kilometres (25 mi) long, 2–10 kilometres (1.2–6.2 mi) wide, and 500 metres (1,600 ft) deep, is the world's largest makhtesh. It is located in Israel's Negev desert, some 85 kilometres (53 mi) south of Beersheba. The makhtesh and surrounding area are home to only one settlement, Mitzpe Ramon, and together form Israel's largest national park.Photograph: Andrew Shiva
