it is a long, bumpy drive from Farmington to Chaco Canyon, yet well worth the effort...here the Chaco culture, actually Ancestral Puebloans, was established about 1,000 years ago, lasting three centuries or so...this is the view from Una Vida back towards the entrance to the canyon...the visitor centre is visible, and behind to the right is Fajada Butte, until recently the location of the famed 'sun dagger', whereat the solstices and equinoxes were marked and celebrated by the ancient astronomers...recent settling of the rock slabs has ended the effect of the light on the pecked spirals
