Caçapava Geopark (Geoparque Caçapava, in Portuguese) is the name of the territory candidate to become a UNESCO Global Geopark. “Caçapava” is a strong name, in both pronunciation (/kɑ:sɑ:’pɑ:vɑ:/) and meaning. Some 2,000 years ago, the Pampean region of southernmost Brazil was inhabited by diverse P amp e a n i n d i g e n o u s p e o p l e s (belonging to the great Charrua ethnicity), adapted to open, grassland- dominated landscapes. Arriving from the northern forests of Amazon and Guairá, the guarani people, adapted to the jungle-dominated landscapes, invaded and conquered many territories neighboring the Pampa.
