One of the Native American Reservations that Route 66 passes though is the Navajo Nation. This rock formation (known in Navajo as: tségháhoodzání or, the rock-with-hole-through-it), lies the city’s Memorial Navajo Tribal park, and it is what gave Window Rock, Arizona, the nation’s capitol city, its name.
In the park there is a stature dedicated to the tribe’s veterans (Native Americans take their citizenship and military service VERY seriously — as part of being modern-day warriors) and in particular the statue commemorates the Navajo Code talkers who were instrumental during WWII. 
Adjacent to the park are MOST of the buildings that constitute the government of the Navajo Nation.
For those who don’t know, the tribes are Dependent Sovereigns with the right to govern themselves, to a point (and that point has varied). This part of the town is where you’ll find the Navajo Nation’s Counsel Chambers,
The offices of President and Vice President
the tribal courts (Each tribal nation has its own Supreme and District courts), and the central location for the Nation’s police force (tribes are controlled by Federal laws but not State).
