One of nature's works is the Ammonite Wall, which is on the right just as you finish the descent on route 40 from Mitzpe Ramon into the crater itself (on its northeastern edge). A sign indicates a distance of 5 km (3 mi), which applies to the marked hike in the crater (for fit walkers only—take water). The rock face, which is actually part of the crater wall, contains hundreds of ammonite fossils, which look like spiraled rams' horns and are indeed named for the Egyptian
god Ammon, who had the head of a ram.
