Blanca Peak and the Boundary of the Diné World

Blanca Peak rises to fourteen thousand three hundred and forty-five feet in the Sangre de Cristo range at the southeastern corner of Colorado. To geologists, it is a Laramide uplift, granite and metamorphic rock pushed skyward by plate convergence sixty to seventy million years ago. To the Diné people, the Navajo Nation, it is Sisnaajiní, the Sacred Mountain of the East, and it is one of the four peaks that mark the boundary of Dinétah, the traditional Navajo homeland.

The Diné cosmology established four sacred mountains as the corners of the world given to the Navajo people. Blanca to the east. Mount Taylor, Tsoodzil, to the south. San Francisco Peaks, Dook'o'oosliid, to the west. Hesperus Peak, Dibé Nitsaa, to the north. Within those four points lay the land the Holy People had prescribed for the Diné. The mountains were not metaphorical. They were actual geographic boundaries that organized Diné land use, ceremony, and identity for centuries before any outside government drew a line on a map.

The Navajo Nation today occupies roughly seventeen million acres within those boundaries, the largest tribal land area in the United States. But the Long Walk of eighteen sixty-four, when the United States Army forcibly removed the Diné to Bosque Redondo in eastern New Mexico, was explicitly an operation to push them outside those four sacred mountains and sever the connection between the people and the geography they understood as foundational. The Diné were allowed to return in eighteen sixty-eight under the Treaty of Bosque Redondo. They walked back through the passes, back inside the four mountains, which is how the return is described in the oral tradition: coming back inside.

Blanca Peak sits at the edge of Great Sand Dunes National Park. The Diné relationship to this landscape predates the park designation by centuries, and it continues.
