Passage: Makhtesh Ramon (Hebrew: מכתש רמון; lit. Ramon Crater/Makhtesh ; Arabic: وادي الرمان‎) is a geological feature of Israel's Negev desert. Located at the peak of Mount Negev, some 85 km south of the city of Beersheba, the landform is not an impact crater from a meteor nor a volcanic crater formed by a volcanic eruption, but rather is the world's largest "erosion cirque" (steephead valley or box canyons). The formation is 40 km long, 2–10 km wide and 500 meters deep, and is shaped like an elongated heart. The only settlement in the area is the small town of Mitzpe Ramon (מצפה רמון, "Ramon Lookout") located on the northern edge of the depression. Today the area forms Israel's largest national park, the Ramon Nature Reserve.
