Chilean explorer and photographer Cristian Donoso followed in the footsteps of early 20th century missionary, Alberto de Agostini, to recreate his images of Patagonia's glaciers taken over a century ago. His photographs reveal how climate change has melted the glaciers. De Agostini left an archive of 11,000 images of Patagonia. This one, taken in 1914, shows the Marinelli glacier in Tierra del Fuego's Ainsworth Bay.

When Donoso and expedition partner Alfredo Pourailly visited in 2018, there was no sign of the Marinelli glacier from the same vantage point at the same time of year.

Patagonia's ice fields make up the largest body of ice outside of Antarctica and looked very different when de Agostini explored the region over a century ago.

In 2018, Patagonia's Ainsworth Bay was ice free. These calm waters were once covered by the Marinelli glacier.

A century ago, de Agostini took this photo of the Negri glacier on one of his many expeditions into the wilds of Patagonia.

Donoso and his team sailed through the fjords of Patagonia, reaching their final destinations on foot to recapture de Agostini's images.

This panoramic landscape taken in 1914 by de Agostini shows the Reina Isabel II glacier in Tierra del Fuego. Agostini spent years documenting previously unexplored parts of Patagonia.

The Reina Isabel II glacier is now a fraction of its former size.

De Agostini captured this image of the Luis de Saboya glacier in Tierra del Fuego in 1913.

Donoso and Pourailly recaptured Agostini's image of the Luis de Saboya glacier -- now with a lot less ice -- on their two week expedition in 2018.
