verified Ungraded High flood risk São Roque de Minas, MG

Technical quartzite descent inside Serra da Canastra National Park. Nine rappels through a winding gorge with deep plunge pools, well within waterfall-rappel character rather than dry slot.

Morphology is waterfall-driven, not dry slot, but the gorge is narrow and water-cut between drops which earns the inclusion. First integral descent recorded August 6, 2015. ICMBio rules in the Canastra park are evolving; even where ropewiki marks red tape unknown, expect to need authorization for technical descents inside the park boundary.
