HaMakhtesh HaGadol (lit. The Big Crater) is located in the Negev desert not far from Yeruham.
Makhtesh is a geological landform considered unique to the Negev desert of Israel and the Sinai peninsula of Egypt. A makhtesh has steep walls of resistant rock surrounding a deep closed valley which is usually drained by a single wadi. The valleys have limited vegetation and soil, containing a variety of different colored rocks and diverse fauna and flora. The best known and largest makhtesh is Makhtesh Ramon.
Although commonly referred to as “craters,” these formations are “erosion cirques” (steephead valleys or box canyons). Craters are formed by the impact of a meteor or volcanic eruption, whereas makhteshim are created by erosion.
Despite what’s written in Wikipedia (the quote above) our instructor explained that this is a common misconception and there are machteshim in other parts of the world as well.

HaMakhtesh HaGadol AKA Makhtesh Hatira since it was drained by one river, Nahal Hatira.
Though it’s called Makhtesh Gagol (gadol means big in Hebrew) it’s the second largest after Makhtesh Ramon. It’s called big since it was discovered and named before Makhtesh Ramon.

Israel National Trail
Israel National Trail passes through HaMakhtesh HaGadol and our gide took us for about a two hour hike. After several minutes we found this:

They are gregarious and noisy, with a call that resembles a wolf whistle. They are also omnivorous.
