ABOUT GEOPARK

 

Bryn Gwyn Geopark is a natural reserve where you can enjoy the adventure of scientific exploration in a real field experience.

Operated by MEF, the Geopark offers a tour in of this site in Patagonia, traveling through the past in 40 million years. There, you will see fossils -partially exposed in the ground- of specimens found by researchers over the years.

These specimens tell a story of geological and climate changes that affected the region since the mid-Paleogene (Tertiary period) to the present.

The elevated trail is easy for almost everyone, and the field station offers restrooms and other visitors resources to fully enjoy your visit.

PALEONTOLOGICAL TRAIL

 

From the Field Station, the trail goes up and into the depths of the Tertiary Period. The first fossils of insects and mammals tell us about before the lifting of the Andes, which occurred during the Miocene.

 

Patagonia was an extensive savannah. The climate, warmer than today, was disturbed by frequent volcanic eruptions during this period, depositing large amounts of ashes on the ground.

 

"Diving" in the Tertiary

But then, another fact became in a dramatically change on the landscape: the invasion of sea water over the continent. Fossils of whales, dolphins and other marine species evidence that this area was once under the sea.

 

A little further up, we find a larger site of oyster fossils: why? the sea had begun to back off.

With the resurgence of the ground another geological phenomenon is observed: recent glaciations during the last 100.000 years shaped the valley and cut the geological strata allowing us to witness this fascinating story.
