One of the interesting things I kind of knew and this map confirmed: If you put in Austin, TX and look at the Jurassic and Cretaceous periods, you'll see Austin was oceanfront property for tens of millions of years. I-35 was built right on this beachfront area and acts as the dividing line between ancient oceanbed and ancient land. The result of this is that building an in-ground pool is much cheaper if you live east of 35 than if you live west of 35.
- parasanti 7y agoI was just looking at the same thing. Also another bit of info...if you live east of 35, you only need 10 acres for an agriculture exception. West, you need 15 acres. Those pesky rocks.

- Shivetya 7y agopretty much why a big industry in middle Georgia is sand, the railroads built to support that industry serve pecan farmers now; there is still sand being sold. So two notes. 1) It would be nice to track glaciers, they used to be truly massive during past history and it would be interesting to see them recede and more land being above water level 2) Going the other way would be interest too, what would the earth look like in 100,000 or million years?
- bluedevil2k 7y agoRegarding 2, I think the landmass location would be predictable, but the sea levels wouldn't.

"How the Cretaceous coastline of North America affects US presidential elections ... Along that ancient coastline of a shallow sea, plankton with carbonate skeletons lived and died in massive numbers, accumulating into large chalk formations on the bottom of the sea. When the sea level dropped and the sea drained through the porous chalk, rich bands of soil were left right along the former coastline. When that area was settled and farmed in the 19th century, that rich soil was perfect for growing cotton. And cotton production was particularly profitable, so slaves were heavily used in those areas."
