Appears on John Senex's map of 1710 and most early Spanish maps as an area in the eastern part of central Arizona running into New Mexico west of Rio Grande. Also marked "Apacheland" on some early American maps. Coues describes it as "The indefinite area or region n Arizona and New Mexico in which Apaches roamed."
Father Kino in his diary, according to Bolton, says: "Apacheria which lies to the north and northeast of us and extends northwest to the very large Colorado river or Rio del Norte above the 35th, 36th, and 37th parallel and beyond. By way of this same Apacheria we shall be able to enter to deal with New Mexico and its newest provinces."
