In my continuing effort to ignore the ongoing demise of the human race (shorter news: you and your posterity are soooooo screwed), here's a very cool satellite image of alluvial fans:(Click for macrification) Below is a similar example, here on earth. Yeah, the one above is on Mars. If you look carefully, you can find quite a number of impact craters on the image- for example, there are four near the top middle.(The above is also macrifiable if you know the trick.) Anyone recognize the location of the earthly image? Bajadas (Spanish 'j,' pronounced "buh-hah'-duh") are a series of alluvial fans coalescing to form a broad wedge or ramp, so in both images, it's not inaccurate to call the landforms alluvial fans, but it would probably be more accurate to describe them as bajadas.
