Community Overview

Gray Mountain sits on Navajo Nation land in northern Arizona, where 98% of the 59 residents are Native American. This remote community spans 462 square miles of high desert plateau along Highway 89, the historic corridor between Flagstaff and the Grand Canyon's east entrance. It's a PO Box Only Zone. There's no street delivery here, and no alternative exists across this vast territory.

Cameron: A Shared Identity

The post office also accepts mail addressed to Cameron, a name familiar to travelers who stop at the Cameron Trading Post before entering the Grand Canyon. Both Gray Mountain and Cameron are valid mailing addresses for this ZIP code. Highway contract carriers handle the limited delivery service, traveling the single designated route along Highway 89.

Household and Family Patterns

Only 20 households occupy this territory. The population-to-household ratio of 2.95 suggests extended family living arrangements common in Navajo communities. Median household income sits at just $2,500, and median home values are $30,800. None of the 37 adults over 25 hold a bachelor's degree. These figures point to extreme economic hardship.

Housing and Economy

Of the 32 housing units, 12 sit vacant and 9 are seasonal. That's 28% seasonal vacancy, indicating some structures serve as occasional shelter for families with homes elsewhere on the reservation. The 4 local businesses employ 87 workers, likely connected to highway services and the Cameron Trading Post area. For the small permanent population, the post office isn't just convenient. It's their only connection to mail service.
