Established in 1962, the National Natural Landmarks Program each year designates a handful of sites in public or private ownership that embody the best of the nation’s natural heritage. And the newest landmark is a West Texas property.

As archeological techniques and perspectives evolve, artifacts collected decades ago can be as revelatory as new finds.

Chirping frogs are typically less than an inch long, and you could mistake their whistling, trilling calls for an insect’s. But these little creatures have an epic story, one that distills the deep mysteries of biodiversity.

More than any mountains, mesas or canyons, the region's sand dunes distill the desert’s defining phenomenon, drought.

Five years ago, archeologists began excavating the San Esteban cave south of Marfa, searching for evidence of the Big Bend's earliest inhabitants.

At sunset tonight, a few thousand Mexican long-nosed bats will fly from a cave high in the Chisos Mountains. They’ll disperse to feast on agave nectar — pollinating the iconic plants in the process. These “agave bats” are deeply imperiled by human impact but for now, they’re holding their own.

With the return of black bears to West Texas, researchers are tracking their movements and studying their habits. And with careful science, they're hoping the bears can once again flourish in the region.

New research on mountain lions in the Davis Mountains offers a rare glimpse into the secretive lives of these "ghost cats."

Agave-roasting was a mainstay of life in prehistoric West Texas. And new research suggests the practice was as much about celebration as it was sustenance.
