Historical River Channels

If you measure the contours of a river valley with Lidar (like radar with lasers), you get a beautiful map of all the historical river channels. The image above was taken from a poster of the historical channels of the Willamette River...click through to see the whole thing. See also Harold Fisk's meander maps of the Mississippi River.
