The northwestern portion of Louisiana is culturally and economically attached to Northeast Texas and Southwest Arkansas. Combined they comprise the Ark-La-Tex area, just as the northeastern portion of Louisiana, Southeast Arkansas, and Northwest Mississippi are known as the Ark-La-Miss. The Louisiana Central Hill Country, the hilly areas of LaSalle, Grant, Winn, Caldwell, Natchitoches, Jackson, Lincoln, and Bienville parishes,[3] extend into portions of North Louisiana's border with Central Louisiana.
