New county seat given new portmanteau name
On this day in 1902, Dalhart became the county seat of Dallam County. The name is a combination of the names Dallam and Hartley. The original settlement began where the Chicago, Rock Island and Pacific Railroad crossed the tracks of the Fort Worth and Denver line, on the boundary between Dallam and Hartley counties. It was first known as Twist Junction. Subsequently, it adopted its first portmanteau name, Denrock, derived from the names of the two railroads. When the ever-unpredictable postal authorities objected, the name was changed to Dalhart.
