Cavernas do Peruaçu National Park - Brazil

 One, two and now a third card from a national park also classified as UNESCO site. The classification of this one took place last month, and Brazil added another site to its list of UNESCO sites.  

The Peruaçu River Canyon is located in the Peruaçu Caves National Park in northern Minas Gerais, perhaps the Brazilian state from which I have the most postcards. However, despite having received many postcards from there and purchased many others there, I didn't have a single postcard from the park. Luzia didn't wait long to surprise me, and the day after the site was classified, she wrote me this postcard. It was a surprise in celebration of Postcrossing's 20th anniversary. In fact, she says she was participating in the Postcrossing lounge on the anniversary! Thank you, Luzia.

The park features dramatic karst landscapes, a complex of more than 200 cataloged caves, archaeological sites with human remains up to 12,000 years old, cave paintings, and a rich biodiversity.

(...) the park’s horizontal cave systems, formed in carbonate rock, reveal striking speleothems, collapsed dolines, limestone arches, and underground rivers. Developed in the stable São Francisco craton, the landscape reflects major climatic and geological changes from the Plio-Pleistocene. The park lies at the intersection of the Cerrado, Caatinga, and Atlantic Forest biomes, supporting over 2,000 plant and animal species, including many threatened ones. - in: https://whc.unesco.org
