Deaf Smith County comprises approximately 1,497 square miles of level prairies and rolling plains on the western edge of the Llano Estacado. Its loam soils, ranging from deep chocolate to sandy, support 00 feet above sea level; the minimum average temperature is 22° F in January, and the average annual maximum is 93° in July. The average annual rainfall is 17.37 inches, and the annual growing season averages 185 days.

The western prairies were home to Plains Apaches, Comanches and Kiowas who were forced out in the Indian wars of the 1870s. Shortly thereafter ranchers began to appear in the area, and in 1876 the Texas legislature formed Deaf Smith County from the Bexar District.
