Bottomland Hardwood Forest
Bottomland hardwood is a forest defined by flooding. The trees here — overcup oak, water hickory, black willow, bald cypress at the wettest edges — are the species that can stand having their roots underwater for weeks at a time, and the forest sorts itself into bands by how long each spot stays wet.

Native Pecans
The pecan is the state tree of Texas and it is native to exactly this ground — river bottoms with deep, well-drained silt that floods occasionally and drains fast. Wild groves along the Colorado and the Brazos fed people here long before anyone planted an orchard, and the trees are long-lived enough that some standing now were mature before the first Anglo colonists arrived.

Spanish Moss at Its Western Edge
The gray strands hanging from these bottomland oaks are Spanish moss, which is neither Spanish nor a moss — it is a bromeliad, a relative of the pineapple, and it takes no water or nutrients from the tree it hangs on.

The Armadillo's March North
The nine-banded armadillo is not an old Texan. It crossed the Rio Grande in the 1800s and has been expanding north and east ever since — through Texas, across the South, and now into Nebraska and Illinois — one of the fastest range expansions of any American mammal.
Nature
The Colorado at Columbus
The Colorado has cut a deep, tightly curved loop here, and the town sits inside the bend. Rivers on a flat coastal plain normally wander freely, but this one is entrenched — it cut down into older terraces rather than sliding sideways, which is why the meanders are so pronounced and so fixed in place.
Nature
The Colorado River Valley
The highway follows the Colorado from here most of the way to Austin, and the river is doing something unusual for a coastal-plain stream: it runs in a valley it cut for itself, with distinct terraces stepping down to the modern channel.
Nature
The Monarch Funnel
Texas is the neck of an hourglass for monarch butterflies. Nearly the entire eastern North American population passes through the state twice a year, funneling down in autumn toward a handful of mountain fir forests in Michoacán and coming back north in spring.
Nature
The Post Oak Savannah
This belt of scrubby oak and grass is a genuine transition zone — the band where the eastern forest gives out and the prairie begins, running northeast across Texas between the Piney Woods and the Blackland.
