If you were to go back thousands of years to the site of Wadi Mujib, in central-eastern Jordan, all you would see is the sea. It is the sea that has left its mark on the rock, creating canyons that can be more thana kilometre deep. These canyons are criss-crossed by the River Arnon, which rises in the Gilead mountains before flowing into the Dead Sea after 800 kilometres.
This makes the Mujib Reserve the lowest nature reserve in the world, at over 400 metres below sea level! This environment, where water and rock meet, is home to a rare wealth of biodiversity.
