To the north of Ralls is the small community of Cone, Texas and further north is a narrow portion of Blanco Canyon, where the Spanish explorer Francisco Vázquez de Coronado and his army are believed to have camped in 1541. To the south of Ralls is the Caprock Escarpment which marks the break between the Llano Estacado and the rolling plains carved by the tributaries of the Brazos River.
