Since the publication, in 1891, of Mindeleff's maps and descriptions of five ruined pueblos along the rim of Antelope Mesa, the Jeddito Valley in the Hopi Reservation, northeastern Arizona, has been known as an interesting archaeological area. Subsequent short field trips by Fewkes, Russell, Hough, Kidder, the Cosgroves, Gladwin, Morris, and Hargrave have furnished further information about the large sites, called attention to the great number of small sites, and emphasized the archaeological importance of the region as a melting pot in which were blended elements of cultures and probably peoples from many directions. San Juan, Little Colorado, and Puerco met here; the San Francisco Mountains are within sight to the west, and a Rio Grande tongue is still to be heard on the Hopi mesas.
