Alamosa County was carved from Northeastern Costilla County on 8 March 1913.

Though Native American cultures were present for thousands of years, the discovery of gold and silver in 1870 is what brought people and settlements to the area. Once here, they remained and began to farm and ranch. The coming of the railroad also increased the number of new settlers. Zebulon Pike explored the area in 1807 and was particularly interested in the Sand Dunes. The area wasn't really settled permanently until about the mid-1800's. In 1878, the new railroad made a stop near a grove of cottonwoods, leaving behind a group of new settlers and their things. The name, Alamosa, is Spanish for cottonwood grove. The new little settlement was named for the grove of trees. Soon more settlers came and tracks were put down spreading out in all directions from the town. Alamosa became a center for commerce and trade in the valley.
