Upper Blanco and Largo Canyons in Rio Arriba and Sandoval Counties, northern New Mexico (Fig. 5), are in an area known to modern Navaho Indians as dinetah, “Navaho country,” “Navaho homeland place,” and is recognized by them as the homeland of their ancestors. A number of Spanish records also refer to it as Navaho country. Anthropologists have, therefore, turned to the region as a source for data on the early Navahos. Surveys and some excavations of sites have been made.
