Texas General Soils Map

Here's a really cool map of the different soils found across the state of Texas.  This map is provided by the US Department of Agriculture Natural Resources Conservation Service.

It's fascinating to me how the soils change across the state.

Notice the second page that describes each soil classification. In particular, note that the Gulf Coast Prairie is dominated by "well-developed, clayey soils with high shrink-swell properties."

That's us, Houston.
