In 1749, Spain settled the area we now call the Rio Grande Valley, thus was born the Tejano. Because of the remoteness of South Texas at the time and its proximity of Mexico, Tejano culture was very much tied to the Mexican states of Nuevo Leon and Tamalipas. These ties continue today and are a strong influence on the Tejano culture.
The first Spanish map of the Grand Canyon region was produced by Fray Silvestre Velez de Escalante in 1775. From New Mexico at the bottom (east) he depicts the presence of, distances between, and/or populations of, the Zunis, Mescalero Apaches, Comanches, Navajos, Utes, Hopis, and farthest west, the Cosminas (Havasupais and Hualapais).
