Events with defined beginnings and conclusions can cast shadows far beyond their shelf life. On the Southern Cone, a six-year war marginalized some and empowered others—its legacy enduring. Within the resource-rich Triple Frontier, the Itaipu Dam stands as a beginning to a reversal of fortunes, a rebalance of power, a shift in sovereignty. As these man-made forces reshape the landscape, Iguazú Falls flows on—oblivious to its place at the confluence of geopolitical struggle, unmoved by the changing winds of power. Spend a day on each side of the falls, then cross into Paraguay with a guide, and witness history not as memory, but as a living force.
