Here’s another view of this storm, taken just south of the Canadian River.

The geography here is known as the Breaks, rough and rugged terrain that’s very different from what you’d expect to see on the Plains. Barry Lopez’s excellent book Home Ground: Language for an American Landscape describes it this way:

Breaks, in the western United States, are tracts of rough, broken land, similar to badlands, that are of little commercial or utilitarian value – stretches of terrain, cracked and fissured by arroyos and ravines, nearly impossible to negotiate for any distance on foot or by horse. A dramatic example is found in the Texas Panhandle, where the course of the Canadian River abruptly fractures the smooth face of the Llano Estacado into a virtual bedlam of steep hills and tight passages.

There’s bedlam, too, in the sky above the breaks.
