This particular area doesn't have the best resolution image data but you can see it well enough I think. This is the Rio de las Chinas in Chilean Patagonia (just east of Torres del Paine National Park). I did field work in several mountains surrounding the course of this river and always liked admiring it while eating lunch on a ledge (or, more typically, cowering in the fetal position while the wind beat the life out of me.)
Flow is from left to right. Note the change from braided (or maybe anabranching?) morphology with multiple channels separated by bars to the beautiful meandering morphology, including some oxbows. Here's a photograph I took from above the meandering section. FlashEarth link: http://www.flashearth.com/?lat=-51.0062&lon=-72.579491&z=12.9&r=313&src=msaP.
