Río de Las Minas is a river located west of Punta Arenas in the Magallanes Region of southernmost Chile — one of the most remote and geologically rich corners of South America. The river flows through a landscape shaped by Patagonian geology, with exposed formations that have yielded significant paleontological discoveries, speaking to the deep natural history of this rugged terrain. The surrounding environment is characteristic of southern Patagonia, with windswept terrain, native vegetation, and the dramatic geography that defines the far south of Chile. Its proximity to Punta Arenas makes it one of the more accessible waterways in an otherwise vast and sparsely populated region.
