The Navajo reservation, which spreads across northwestern New Mexico, northeastern Arizona, and southern Utah, is comprised of seven major judicial districts, and many smaller chapters within each district. In Hillerman's 1984 novel SACRED CLOWNS, Greasy Water Trading Post, a fictional location, is the site of the theft of a number of antique items. Although there is no such district, chapter, or trading post in Navajo Nation territory, some names come close, such as Sweet Water and Greasewood Springs, so it can be assumed that real places provided the inspiration for the invention of this imaginary one.
