The Anasazi Heritage Centers new winter-season exhibit Ancient Skywatchers of the Southwest showcases prehistoric astronomical markers in the Four Corners region. The images are the work of explorer and photographer John Ninnemann, and will be displayed from Nov. 23, 2012, through April 27, 2013, in the museums Special Exhibit Gallery.
The Anasazi Heritage Center will host an opening celebration with a book signing and lecture by Ninneman at 1 p.m on Sunday, Nov. 25. Ninnemann will sign his book, Canyon Spirits: Beauty and Power in the Ancestral Puebloan World. During the lecture, he will explain the tradition of the skywatcher among the Pueblos and how it illustrates the importance of astronomy in the early Southwest.
Ninnemann has spent decades studying the rock art and architecture at remote archaeological sites. His work captures significant alignments of the sun and moon that mark important points of the Pueblo year. Ancient Skywatchers of the Southwest was produced by museum of the Center of Southwest Studies at Fort Lewis College in Durango.
People throughout the ancient world especially those who survived by farming, such as the Ancestral Puebloans paid close attention to the annual rhythms of the earth and the corresponding movement of heavenly bodies. The longest and shortest days of the year were often commemorated by annual ceremonies among early people. Marking the years mid-points at spring and fall equinox likewise helped determine ideal times for planting and harvest.
The Ancestral Puebloan people had a deep interest in celestial events. Their understanding of astronomical cycles is reflected in the architecture and rock art they left behind. Some buildings included oddly-located windows through which the rising sun would appear on a specific date. Sometimes a shadow or a sunbeam falling across a rock art image would signal the change of season.
More remarkable is evidence that builders of Chimney Rock Pueblo near Pagosa Springs (now a National Monument) anticipated a cycle of the moon that only repeats every 18.6 years. The lunar standstill moonrise at its southernmost point is rarely noticed, even by modern people, and its meaning to the Chimney Rock people is a continuing mystery. The pueblos builders chose a site where the standstill moon rises between a pair of natural stone pillars. Periodic construction and remodeling at Chimney Rock took place mainly during lunar standstill years.
The Anasazi Heritage Center is an office of the Bureau of Land Management, and is headquarters for Canyons of the Ancients National Monument. The museum is open daily from 10 a.m. to 4 p.m., with free admission November through February. For more information, visit the Centers website at www.co.blm.gov/ahc or call 970-882-5600.
