Postcard: Iguaçu Falls, western Brazil

Iguaçu Falls in western Brazil is probably the most powerful sight I’ve ever seen. No photo can communicate the thunderous noise made by this 1.67-mile horseshoe of massive waterfalls, which peaks at 269 feet from top to bottom. Standing right underneath them, as I was when I took this shot on Thursday, makes it hard to think. Which is kind of the best part.
