The Defiance Plateau of northeastern Arizona declines gradually from its origin, the Chuska Mountains of New Mexico. Route 191 runs where the Defiance Plateau merges with a valley of the larger Colorado Plateau. The Black Mesa escarpment forms the western valley wall and is clearly visible from Canyon de Chelly visitor center. You can see the valley and escarpment in my post Canyon of Music, Wind, Light.
Carved into the Defiance Plateau, the high cliff canyon walls of Canyon de Chelly at intervals belly out into wide alcoves. For thousands of years, the land between the walls was farmed. Here is a photograph from our 2008 canyon visit, visible are fields, farm equipment, shed and sport utility vehicle (SUV). Look closer for the hogan, adjacent to the shed, and, on the lowest sandstone shelf on the left, white goats.
Here is a quote from the reference link provided at the end of my post:
“The massive, high cliffs that form the walls of the canyon are De Chelly Sandstone. The De Chelly Sandstone consists of sand deposited in dunes in a subtropical to arid environment in Early Triassic time (about 250 to 230 million years ago).”
In this photograph the goats jumped off the shelf to graze, around them are the two forms of De Chelly Sandstone. 230 million years ago winds driving across the dry lands, piling the eroded bits of ancestral rocky mountains into dunes hundreds of feet high. The in-stratified rock cliffs are the body of those dunes, converted to stone over the eons. The cliffs are visible in both photographs. The dark stains are called desert varnish. Read more about desert varnish in the first posting of this series, “Portrait of a Navajo Guide.” The rock in the foreground appear formed from an orderly pile of stone plates, this appearance is called stratification. Another name for it is Cross Bedded Sandstone, formed from wind blowing across the dunes.
That entire, northeastern, side of the alcove is Cross-bedded sandstone. Click on any one of the following photographs for a larger version, to peruse the detail.
A fascinating detail in these photographs, the subject of this post, are human figures rendered tiny by the distance and the enormous maze of sandstone.
It is four generations of a Navajo family, fathers, mothers, children of all ages down to infants in carriers. My wife Pam, myself and our Navajo guide watched in wonder as they made their way down to the canyon floor.
Their progress was slow and careful. Everyone kept together. Nobody left behind.
Here they inch along a high ledge.
Descend from one ledge to the next.
Most amazing of all, the first person down is an elderly woman wearing sports shoes, steadied with umbrella, accompanied by a pre-teen girl. Her progress steady and sure from years of experience.
Our guide knew the family. He and they chatted in the Dine language. The were travelling for a birthday party.
