It has only been in the last 75 years that we have made time a commodity by wearing wrist watches. Prior to that, those who could afford to wore pocket watches, cumbersome yet useful items once the owner modified his clothing to accommodate storage. Before these inventions, time was measured in days or months and was seen as an enabler instead of our present day view of time as an external, unseen force showing us our limitations and failures.
A thousand years ago in the Four Corners Region of the American southwest, time was experienced as a facilitator and an all-encompassing personal encounter. From the very beginning, these ancient ones were in search of time itself - their mythology stories available to us today claim that in the time after entering this world and before they occupied Chaco Canyon, the Ancestral Puebloans were in a constant state of migration. They moved in a south by southeastern direction using wooden staffs to measure their travel against a certain star that was only visible at certain times of the year. Finally, when they reached Chaco Canyon they found a physical manifestation of time on earth.
Only recently with our computers and space-based telescopes have we determined what these stone-aged people knew with sticks and naked-eye star-gazing: Chaco Canyon is a calendrical station which is naturally aligned for calculating the 19 year lunar cycle. To confirm (and ultimately celebrate) this, Chacoans built redundant observatories for anticipating multiple astronomical dates which were important to them, their religion and their way of life. Simultaneously, they developed their culture around physical infrastructure that re-enforced their connection to the cosmos.
This time-consuming effort required patience in order to be effective. Patience on a macro scale can be called commitment and it was this commitment to pursue a common vision that fuelled the Chacoan culture through the vicissitudes of the ages and the ravages of environmental difficulties. During these centuries, they perfected their building techniques and built their concept of time into almost every great house extant as well as their extensive network of roads. Along the way, Ancestral Puebloans developed a thriving system of “international commerce” by importing commodities that buttressed their religious ceremonies and, ultimately, supported their experience of time.
In the end, the same patience required to build this manifestation of time undoubtedly had a great deal to do with the abandonment of their monuments because they understood the difficulties associated with building their world as opposed to existing in it. It was their commitment to this concept of time which prompted them to walk away from their centuries of hard work before they were buried by it.
