Fajada Butte, Chaco Canyon
Atop Fajada Butte Chacoan sky watchers commemorated the movements of the sun and the seasons. Sunlight passed between three boulder slabs onto a spiral petroglyph to mark the suns position on summer solstice, winter solstice , and the equinoxes.
The Chacoans had sophisticated knowledge of the sun and moon as shown by this and other sites.
Sun watching continues to play an integral role in the Pueblo world. Pueblo people use such markers to plan their agriculture, to set the ceremonial calendar, to integrate the physical and spiritual worlds, and to seek balance and harmony for all people.
Our modern interest in this site may have forever impacted it. in 1989, researchers noticed that the light
pattern on the spill had shifted, due to the slight slipping of the slabs.
This may have resulted from human-caused erosion to the base of the rocks.
The main complex of Pueblo Bonita is about three miles away.
