During the 1960s, when Brazilian military engineers pushed the BR-174 highway north toward Venezuela, they cut through Waimiri-Atroari territory and met resistance from the Indigenous nation whose homeland the road violated. According to local history, a Waimiri-Atroari leader named Maroaga took refuge in this underground chamber as the conflict unfolded. Decades later, when the Brazilian state declared the surrounding 374,700 hectares a protected area in 1990, it carried his name. The Caverna do Maroaga Environmental Protection Area sits in the municipality of Presidente Figueiredo, Amazonas, where some of the oldest rock in the Brazilian Amazon holds caves, waterfalls and a record of the past that is both geological and political.
