Dalhart was in the Center of the Dust Bowl, an area adversely affected by a long period of drought and dust storms during the Great Depression of the 1930s. It was here that Tex Thornton operating on the now debunked concussion theory coaxed today's inflation adjusted equivalent of $1 million from the locals on claims he could fire rocket-powered explosives into the clouds and cause rain. Dalhart is also known as the "XIT City" because of its relationship with the historic XIT Ranch. The ranch was a 3,000,000-acre (12,000Square kilometers) plot of land traded in exchange for the construction of the Texas State Capitol in Austin. The ranch was dissolved in 1912, but its history is celebrated with the city's XIT Museum and the XIT Rodeo and Reunion. Dalhart is a city in Dallam and Hartley counties in the U.S. state of Texas, and the county seat of Dallam County. The population was 7,237 at the 2000 census.
