Well, we entered Torres del Paine National Park today to do the daunting three/four/five day trek through these amazing mountains. Resulting partially as the result of a granite injection into the Andes mountains, they remain virtually untouched (though hundreds of thousands of tourists visit each year, and the number is rising). I'm very excited to see these - I've been looking forward to them since we started. It'll be a hard hike, but the views are supposed to be unparalelled.
This is one of the more powerful waterfalls we saw. All the streams and rivers come from glaciers and, given the cold temps and absence of parasites, make the water safe to drink. It tastes so...clean. So free of anything. It's probably the best water I've ever drunk. Well, maybe a tie with the glacial water I tried on the glacier in Jasper, Alberta as a kid, but I don't remember much about that except that it was SO COLD.
