Steve Lekson to Give Virtual Presentation on the 

“Chaco, North of the San Juan”  

Chimney Rock Interpretive Association (CRIA) hosts a free Lecture Series five times a year to offer the opportunity for the public and CRIA volunteers to gather and enjoy a speaker whose topic typically relates to southwest archaeology, archaeoastronomy and/or Chacoan culture. Experts in the field travel sometimes from far distances to Pagosa Springs to present at this free series, but this month’s lecture series is now happening live and online for all to enjoy from the comforts of your home.  Join us on Thursday, July 16th (MST) at 7:00PM as Steven H. Lekson discusses “Chaco, North of the San Juan .”

“CHACO, NORTH OF THE SAN JUAN”

It is generally held that Chaco did not move north of the San Juan River until 1075.  At several key sites – including Chimney Rock and Far View House – there are hints of earlier Chacoan structures by 1020.  Through the last quarter of the 11th century, Chaco outliers north of the San Juan of Chaco Canyon numbered over 75, including small great houses at the future sites of Salmon and Aztec Ruins.  After 1090, Salmon and Aztec became the main focus of development – some of the largest construction projects in Chacoan history – as Aztec Ruins replaced Chaco Canyon as the preeminent regional center.  Aztec’s architectural icon was enigmatic bi- and tri-walled structures; the new capital was planned around bi-, tri- and quadri-walls.  Similar “outlier” bi- and tri-walls soon appeared across the countryside, presumably demarking Aztec’s region, less than one-third the size of Chaco’s.  North of the San Juan, bi- and tri-walls extended as far west as Montezuma Creek in southeastern Utah – encompassing Mesa Verde and most of the Great Sage Plain – and as far as Genado-Gallup.   Aztec Ruins marks the easternmost, along with single example at Chaco Canyon, built and then razed in what must have been an ideological/political action.   Bi- and tri-walls vanished, along with many other iconic Chacoan forms, after 1300.
