"It's a privilege for me to be here and see this spectacle of nature," says Brazilian tourist Camila Delboni in front of the Iguazu Falls, the largest waterfall system in the world, that swelled to one of its highest level in years. Iguazu Falls, on the Brazil-Argentina border, recorded a flow of 24.2 million liters per second this week, the highest since 2014, according to natural park managers. The park remained open even though a footbridge was inaccessible. IMAGES AND SOUNDBITES
