Irion County, Texas

Irion County is a small, remote stretch of West Texas located not far from San Angelo. Mertzon serves as the county seat, and the population is quite small, with fewer than 2,000 residents calling the county home.

Ranching remains an important part of life here, along with oil production. The landscape is rugged, featuring mesquite, cactus, and rocky hills. Summers can be brutally hot, but the quiet surroundings and wide-open skies offer spectacular views of the stars.

The county was named after Robert Anderson Irion, who served as secretary of state for the Republic of Texas. If you’re lucky, you might even spot a horned toad. Life here is slow-paced and close-knit, with the kind of small-town atmosphere where everyone seems to know everyone.
