machtesh ramon
Hundreds of millions of years ago, the Negev desert was covered by an ocean. Slowly, this started to recede northwards leaving behind a hump-shaped hill. The hump was slowly flattened by water and climatic forces. Approximately five million years ago, the Arava Rift Valley was formed, with rivers changing their courses, carving out the inside of the crater which was a softer rock than that overlying. The crater bottom continued to deepen at a much faster rate than the surrounding walls, which gradually increased in height. As the crater deepened, more layers of ancient rock were exposed with rocks at the bottom of the crater being up to 200 million years old. Today, the crater is 500m deep with the deepest point being Ein Saharonim (Saharonim Spring) which also contains the makhtesh's only natural water source which sustain much of the wildlife in the makhtesh including onagers and ibex.
