This is a look downstream from near our put-in at the 311 bridge. And here's another section of this shelf, a little closer to the bridge...
You can tell that the formation has seen a lot of river wear and tear, given its smooth edges...
Here's a extra-close-up that highlights this smoothness... doesn't it look like a somewhat slumping dessert of some kind?
As I was sitting in my boat at the put-in, waiting for the shuttle drivers to get into their boats, I happened to notice this chromatic anomaly in the generally white-grey-beige expanse...
Isn't that a lovely rosy pink?! Some iron mixed into the calcium carbonate perhaps? Although it's really pink, not red. Maybe some more exotic chemical?
More typical close-ups of limestone show off the myriad mini-huecos made by eons of flowing water and debris...
...some of which are mature enough to start serving as little planters...
Since all of the ground for miles and miles around here is underpinned with this stuff, it's not exactly rare. But you don't always get to see it displayed as attractively as it was on our recent paddle.

Looks like it was a lovely day. Perfect time of the year in Texas, n'est pas?
Yes, it is! You need to come for an extended visit in spring or fall.
