Timelapse Geology

Sorry for the lack of updates recently: our server got hacked over the holidays, and it’s taken us a while to get all the pieces back together again.

Here’s one very cool thing that came to my attention recently: it’s a map of the alluvial valley of the Mississippi River, showing how the course of the river has changed over hundreds (thousands?) of years.

Each color represents a different moment in the river’s long history, and the images are layered up so you can see it all at a glance. What a great idea! I wish I could say I came up with it first, but these maps were drawn up by Harold N. Fisk in 1944. If you’d like to see the whole thing in more detail, there’s a high-resolution version (4 MB, 1000×5871 pixels!) on Flickr.
