School House Rock

I'm reading* this completely bad ass book, which is chock-full of excellent tidbits about our fair city. Here's one:

There are no naturally occurring rocks in New Orleans and the surrounding region. If you'd made me think about it, I might have guessed that, but no one ever made me think about it. The entire area was formed by sediment carried by downstream by the Mississippi, and all of the big stuff dropped out way upriver. By the time you get this far south, it's almost all fine silt and clay. So:
"Any particle in southeastern Louisiana coarser than a few millimeters in diameter was imported by humans."
There you have it. No rocks.

And yet, somehow, we will rock you.

* Though "reading" might imply a roughly linear path through the content. In truth, it's a meandering, semi-random hopscotch, landing on choice bits of text, graphs, and deliriously delicious maps (yes, I'm finally getting my map fix).

    Or fell from space... there's probably a few meteor fragments out there somewhere :)

  2. Ha! Your so called "meteor fragments" are, of course, merely tiny, well-disguised spy-satellites launched and controlled by the ultra-secret Meteoric Metrics for the Man (MMM) agency and, therefore, undeniably qualify as "imported by humans."

    Do not toy with the fallacious-reasoning-ninja.

  3. I love rocks and dirt.

    This all explains why this place is so durned flat.
