This is only tangentially related to geology (rivers and waterfalls - you could even argue geomorphology), but I just stumbled across this article on the Huffington Post that was published last month.
The most dangerous place to swim in the world? It depends on how you might classify danger: shark attacks, piranhas, rip currents, jellyfish? How about being swept over a waterfall? At Victoria Falls, on the border of Zimbabwe and Zambia - perhaps the largest waterfall in the world, visitors can swim in a pool that sits right on the brink of the waterfall, swimming right up to a ledge that drops nearly 360 feet below.
The pictures give me chills!
