Yeah, it\'s an interesting area. I don\'t live on the rez. anymore, but I commute out to Tuba City from Flagstaff. So, I still work there.
At the risk of going off-topic a bit, the Treaty of Guadalupe Hidalgo isn\'t the controlling document for the Navajo Nation. It\'s the Navajo Treaty of 1868. Kit Carson was ordered to \"round up\" the Navajo people in 1864, which he did by applying Sherman\'s tactics to Canyon de Chelley (beautiful place; I used to work out in that area), burning crops and destroying houses. What followed was 4 years of internment at Fort Sumner, New Mexico, and then a treaty negotiated between General Sherman and a Navajo leader, named Barboncito (it\'s interesting, the treaty negotions actually show evidence that Barboncito was trying to bind Sherman with a kind of prayer during their talk). That\'s what established the initial reservation, and it pretty well supercedes the treaty of GH (which I doubt would have dealt with Navajo lands anyway, though I\'m not sure; it certainly specified the boundaries of the original spanish land grants as Pueblo lands.) But of course, we have to take these terms with a grain of salt anyway. \"Reservation\" is a common enough usage, I tend to use it in contexts like this. When speaking to Navajos I am more likely to refer to it as Navajo Nation territory, and in talking with cultural nationalists and traditionalists, we are more likely to say \"Diné Bikeyah.\"
