In this dramatic false-color satellite image, a vast alluvial fan blossoms across the Taklimakan Desert between the Kunlun and Altun mountains in Xinjiang Province.

The left side of the fan in blue is the active side and displays glacial run-off from the Molcha River; the green side on the right consists of older stream paths no longer in use.
