Dallam County

Dallam County sits at the far northwestern corner of Texas, encompassing open plains with Dalhart as its administrative center. The land spreads across grasslands and farmland dominated by ranches and agricultural operations.

The county was established in 1876 and named after James Wilmer Dallam, a lawyer who compiled Texas's first legal reference work. The area quickly became centered on cattle ranching and farming operations.

Ranching and farming shape daily life here, with many families working land that has been passed down through generations. You see grain fields and pastures everywhere, forming the backbone of the community.

Spring through fall offers the best conditions for visiting, when the landscape is greener and travel is more comfortable. The flat terrain makes driving through the region straightforward, though distances between points of interest are considerable.

Rita Blanca National Grassland reaches into the county, creating a green refuge within the otherwise open plains. The county sits at a geographical meeting point where three states converge along its borders.
