In short: Spanning over 2,300 square miles of West Texas, Terrell County is a sparsely populated region defined by its rugged steppe climate. Once a powerhouse for the American wool industry, this remote territory holds a complex history of indigenous heritage, Spanish exploration, and a dramatic economic shift toward oil and gas.

Established in 1905 by the Texas Legislature, Terrell County was carved from Pecos County, encompassing roughly 1.5 million acres. Its development was inextricably linked to the arrival of the Texas and New Orleans Railroad in 1881, which birthed the county seat of Sanderson. Early settlers like Charles Downie transformed the region into a major hub for sheep and wool production. By 1926, the local economy saw historic activity, including a massive sale of 11,000 lambs. While Dryden once served as a vital shipping point for cattle, it has since faded into a ghost town.

The landscape is primarily semiarid, with the vast majority of the county classified as a hot steppe climate. This harsh environment has long been a backdrop for human endeavor, from the ancient indigenous cultures who left behind pictographs and tools in local caves to the 19th-century military expeditions. Captain José de Berroterán explored the area for Spain in 1729, and later, the U.S. Camel Corps traversed the region in 1859 while searching for routes to Fort Davis. The county's geography remains a stark, rural expanse where 100% of the population resides outside of urban centers.

Modern life in the county is marked by both resilience and transition. The economy pivoted significantly after 1957 with the discovery of the Brown-Bassett gas field, which eventually introduced oil production to the area. The region also carries the weight of tragedy, most notably the 1965 flood in Sanderson that claimed 28 lives. Today, the county is recognized for its unique identity, having been officially designated the Cactus Capital of Texas in 1999. With a population of 760 as of the 2020 census, it remains one of the least populous counties in the United States, maintaining a quiet, enduring presence in the Trans-Pecos region.
