In Night of the Coyote (1992), Sheriff Sam Keeyani ( Graham Greene ) gives the definition of Anasazi, as "ancient enemies" and Jessica accepts this. In Murder Digs Deep (1985), Jessica uses the definition of Anasazi as 'the ancient ones," (not enemies) to determine Raymond Two Crows ( Randolph Mantooth ) was impersonating a native expert. The word Anasazi belongs to the Navajo language and means "the ancient ones".
The coordinates used (N36 degrees and 23 minutes, W109 degrees and 12 minutes) from the diary locate a place in Lukachukai, Arizona. This is just north of the Navajo Nation in Eastern Arizona. This is contrary to the location Jessica finds in the atlas.
