Dallam County, Texas

Dallam County is up in the tippy-top of the Texas Panhandle. It’s right on the Oklahoma and New Mexico borders. Dalhart is the biggest town, known for its XIT Ranch history.
This place is all about wide-open spaces and big sky country. Farming and ranching rule the roost here. But it’s not all work and no play.
The Rita Blanca National Grasslands are an outdoor lover’s playground. Birdwatchers flock here (pun intended) to catch a glimpse of prairie chickens. There’s an old-school charm to Dallam County.
