Marrah Mountains and Meidob Volcanic Field, Sudan12.9N 24.2E
The darker brown patches interrupting the otherwise golden tan terrain of the Darfur region of western Sudan are areas of mountains and volcanic fields. The brown zone located in the center of the image is the Marrah Mountains, a range of volcanic peaks created by a massif that rises up to 3,000 m. It is located in the center of the Darfur region, specifically within Dar Zagahawa and neighboring areas. The highest point is Deriba Crater. The upper reaches of the massif is a small area of temperate climate with high rainfall and permanent springs of water.
The brown patch, slightly darker in color, situated to the northeast of the Marrah Mountains is the alkaline Meidob volcanic field. It is a volcanic field at the northeast end of the Darfur volcanic province, adjacent to the Kutum volcanic field. It covers an area of 5000 km² with nearly 700 late Cenozoic vents.
