NASA astronaut Don Pettit has shared a remarkable photograph of the Betsiboka River estuary in Madagascar, highlighting the dramatic impact of deforestation on the region. The bright red color of the river is due to iron-rich sediments washed into the waterway by erosion, creating a visual reminiscent of arteries in the retina.

The estuary is a excellent example of rapid coastal change due to extensive deforestation, according to NASA’s Earth Observatory website.
Pettit has a sharp eye for dramatic vistas like this, and he’s usually quick to find a camera to record them. A similarly striking waterway image shared by Pettit last year shows moonlight reflecting off of locations in the Amazon basin in South America, a scene that he said looked like “flowing silver snakes.” Another image, showing light reflecting off SpaceX Starlink satellites, reminded him of “cosmic fireflies.
