Dalhart, Texas
Dalhart sits on the high, flat plains of the far northwestern Panhandle in Dallam County, about 70 miles northwest of Amarillo. The town grew as a railroad and ranching center and lies at the heart of country once part of the vast XIT Ranch, whose legacy the community still commemorates. Today the surrounding shortgrass plains support large-scale cattle feeding and dryland and irrigated farming, and the Rita Blanca National Grassland lies nearby.
