Just returned from an incredible guided geology field trip with the incomparable Pedro of Geo Logica. My head is spinning a bit from ingesting 200 million years of Earth’s history in three days. It was mostly the Jurassic and Cretaceous, with some newer stuff too. This was an incredible birthday present.

I was very fortunate to spend the last 5 days in Portugal, as part of Geo Logica ‘s first iteration of the “Salt Diapirism and Sediment Interaction” field course. Many thanks to Pedro Barreto, Ricardo Pereira, Prof. Ian Davison and all the other participants for the cool localities and the great discussions (and so. much. fantastic. food!)

A superbly organised geological and gastronomic experience. Spectacular exposures of diapirs and related features with a backdrop of the stunning west and south coasts of Portugal. A fantastic group of professionals for stimulating discussions. Hats off Geo Logica and highly recommended for anyone considering the second iteration!

Had a fantastic time with my grandchildren while discovering more about the amazing history of our planet. They loved to see and learn how the dinosaur footprints were preserved.

Who we are

Pedro Barreto (Founder - Geologist - GeoCreator - Field Trip Leader)

Passionate about being in the nature since toddler, very early got lost in the fabulous meanders of Serra de Sintra, near Lisbon. During his childhood collected maps, rocks and fossils and loved climbing trees and boulders at his parents countryside village, where used to spend vacations.

At the age of 15, started climbing together with his middle brother. In a self-taught way, learned basic climbing techniques from equipment brochures bought with piggy bank money.
