Landsat 8 reveal glacial retreat in South America's Patagonia, 2017

Landsat satellites have helped document retreating glaciers worldwide. In this 2017 Landsat 8 image, glacial retreat is revealed in the rugged wilderness region of Patagonia, site of the largest contiguous areas of ice cover outside Antarctica. Satellite imagery supports other evidence that glaciers are melting and receding more rapidly here along the southern tip of South America than ever before in recorded history.
