Imaggeo on Mondays: The colourful sinkhole clusters at Ghor Al-Haditha

Sinkholes that form on the Dead Sea shore at Ghor Al-Haditha, Jordan, often occur in clusters, with many holes packed into a small area. However the visual appearance of neighbouring sinkholes can vary significantly. Mineral precipitation in the foremost sinkhole in this picture, which has no fresh water supply, gives it a garish pink-orange colouration. The larger hole behind has a groundwater-derived supply of fresher (blue) water which allows it to harbour life: ground-nesting birds and frog spawn are both prevalent in the marshy area surrounding the holes. It is slightly paradoxical that such a destructive force can also be an oasis for life in an otherwise barren wilderness.
