Lecture:  The Chamisal Site, a presentation by Thatcher Rogers
January 16, 2022

Artifacts from this site, located in Los Ranchos de Albuquerque, reveal insights into immigration movement, population expansion, and ritual activities during the 13th through 17th centuries.  In his recent work, Thatcher, a 20221 - 22, FCHS Academic Award recipient, has found several very intriguing data, including evidence for potentially some of the earliest supportable glazeware found in the Rio Grande valley.

Thatcher Seltzer-Rogers, PHD candidate at UNM specializing in the archaeology of the southern American southwest/Mexican Northwest region is our presenter for this lecture.  He is a FCHS Academic Award Winner for 2021-22.


Always interesting, Dr. Steve Lekson shares his views

on Chaco in his presentation "Chaco and Me", November 21, 2021

Steve Lekson has stirred up a lot of dust in his time.  For over four decades, much of his archaeological research was focused on Chaco Canyon:  starting with the NPS Chaco Project, followed by surveys of the extensive Canyon region and, later, University of Colorado excavations of Chaco "outliers" at Bluff UT and Chimney Rock, CO.


After these field projects, came the NPS-sponsored multi-year "Chaco Synthesis" (as director of a sizable cast of researchers) and, most recently, "Chaco Landscapes" (junior partner with Drs. Van Dyke and Heitman).

This presentation is an "autobiography" of a set of ideas about one of the most important archaeological sites in the Southwest.


Dating New Mexico Archaeology:  Strong Attractions, Warm Glows, and Sizzle
A Zoom webinar by Dr. Eric Blinman and Shelby Jones

Tying archaeological evidence to calendric time scales requires collaboration. Archaeomagnetic dating uses the Earth’s magnetic field at past times to date material.  Radiocarbon dating is a method to date organic material using the properties of carbon-14.  Both science-based dating methods are in use at the Center for New Mexico Archaeology in Santa Fe.  Both laboratories are at the cutting edges of their disciplines, both serve world interests and both are fun with moments of beauty!

Dr. Eric Blinman is the director of the Office of Archaeological Studies in Santa Fe.  He holds degrees from UC Berkeley and Washington State University and has been involved in Southwestern archaeology since 1979.   During his tenure, he has provided numerous outreach programs for New Mexico Historic Sites.

Shelby Jones will head the archaeomagnetic and radiocarbon dating laboratories at the Office of Archaeological Studies.  She will receive her PhD in geophysics this year and has worked with applications of geomagnetism to archaeology since 2013.

Virtual Webinar Chaco Series

“Gambling at Chaco Canyon: Oral Tradition, Archaeology, and Ancient History in the Southwest".
Presented by Rob Weiner, Sunday November 15


Chaco Canyon in northwestern New Mexico is among the most researched

archaeological sites in the world, but there is still major disagreement over

the organization and function of this ancient center. In this talk, Rob Weiner

explores a new vision of Chaco Canyon informed by engagement with

Diné (Navajo) oral traditions of The Great Gambler which, combined with

archaeological evidence, suggest gambling was a key element of Chaco's

ancient history. Far from the recreational leisure activity of today, gambling

was enmeshed within religious, social, political, and economic life at Chaco.

Considering the role of gambling offers a new lens onto the cultural dynamics

of the Southwest's most infamous archaeological period.

Rob Weiner is a Ph.D. candidate at the University of Colorado Boulder. His research focuses on Chaco Canyon, with particular emphasis on monumental roads, cosmovision, gambling, and Navajo oral traditions. More broadly, he is interested in archaeologies of religion and the role of religion in the longue durée of human history. He has conducted fieldwork in all Four Corners states as well as Turkey.  He also holds positions as a Research Fellow with the Solstice Project, and as a Research Affiliate at Brown University’s Haffenreffer Museum of Anthropology.

EXPERIENCE CHACO CANYON, Presented by Dr. Ruth Van Dyke


We are beginning our Chaco Experience lecture series with the “Chaco Landscapes:

Sensory and Political Engagements with Place” presented courtesy of Dr. Van Dyke and

School for Advanced Research (SAR). We will continue with additional lectures about

Chaco culture prehistory including Chaco ruin outliers.

Archaeologist Ruth Van Dyke presents the 2020 Linda S. Cordell lecture as part of the

SAR's Creative Thought Forum. Dr. Van Dyke shares insights into social, political, and sensorial relationships across the greater Chaco landscape, past and present. She explores how archaeologists can work together with Native peoples to influence the public understanding of contemporary economic/extractive projects, including those in northwest New Mexico.

“Ask An Archaeologist”

Capturing Archaeological Sites Using Aerial Drone Technology,

Presented by April M. Brown, Digital Media Coordinator The Archaeological Conservancy

Over the past few years, aerial drone technology has become a valuable archaeological

tool, especially as the technology has become more affordable.  Drones aid in discovering

previously undetectable features; can be outfitted with specialty sensors; and offer a

large-scale perspective of cultural sites that is impossible to achieve on the ground. 

I recently had the privilege of producing a series of virtual tours for The Archaeological

Conservancy that were featured in the Santa Fe New Mexican.  The first in the series

features James Walker, our Southwestern Regional Director and Vice President, leading

a tour of Arroyo Hondo.  Episode 2 is in production and will feature a guided tour of San

Marcos Pueblo by Conservancy President Mark Michel.  Drones transform these Galisteo

Basin Pueblo Sites from fields of grassy mounds into defined features and site boundaries

that are only visible from the air. 

A side from entertainment, drones can also offer valuable details on potential illegal activity and environmental risks to the site; as well as allow for high-resolution photographs that can also be used in GIS spatial analysis tools.  This Thursday, I will discuss the Conservancy’s virtual tour project, as well as other uses for drones that are certain to be the wave of the future in archaeology. 

April M. Brown recently graduated magna cum laude from the University of New Mexico with a Bachelor of Science in Anthropology, a concentration in Archaeology, and a minor in Geographic Information Science.  Her honors research focused on documenting rock art sites in the Jemez Mountains using drones and spatial analysis tools.  She is the Digital Media Coordinator for the Archaeological Conservancy, a national non-profit organization based in Albuquerque that acquires and preserves cultural sites across America.  In this position, she produces digital content for social media and the web, hosts and mediates virtual lectures, and is responsible for the virtual tour production, editing, and distribution for the Conservancy.

What Ifs: Santa Fe and Southwestern Archaeology

with Dr. Stephen  Lekson

Individuals and institutions of Santa Fe played decisive roles in the development

of Southwestern archaeology. Steve Lekson argues that, for over a century,

southwestern archaeology got the history of ancient Southwest wrong. Instead,

he advocates an entirely new approach—one that separates the archaeological

thought in the Southwest from its anthropological home and moves to more

historical ways of thinking.

The attached lecture traces the remarkable influences of Santa Fe’s archaeologists,

museums, and world-views on the practice of Southwestern archaeology and on

our perceptions of the ancient past. In this entertaining and thought-provoking talk, archaeologist Stephen Lekson asks some “what ifs?” What if: Instead of Santa Fe, Southwestern archaeology centered in Tucson? Or developed out of Ciudad Chihuahua? Or if Southwestern archaeology identified as History, rather than as a laboratory of Anthropology? Or my personal favorite, “What if Hewett had stayed in Greeley, Co?”

Video Tech Note: The webinar will likely start around two to three minutes in. Just re-start the timer by moving the timer slide bar at the bottom of the screen all the way to the left. After the time reset, to remove the busyness of additional YouTube videos on the right side of your screen, just press F (just F) to make it full screen.

In his own words, Dr. Lekson describes himself. “I am an archaeologist, working in the U.S. Southwest. Most of my fieldwork has been in the Mogollon and Anasazi (Ancestral Pueblo) regions, but I’ve also dabbled in Hohokam, Casas Grandes, Jornada, and Rio Grande areas. My principal interests are human geography, built environments, and government; but my current research projects have more to do with migrations (Pinnacle Ruin, in southern New Mexico) and household archaeology (Yellow Jacket, in southwestern Colorado). I am also interested in museums (I am Curator of Anthropology at the University of Colorado Museum of Natural History) and archaeology’s role in American and global intellectual life.”

Stephen  Lekson is the curator of archaeology and professor of anthropology at the Museum of Natural History, University of Colorado, Boulder. He has directed more than twenty archaeological projects throughout the Southwest and has published widely. His most recent books include A History of the Ancient Southwest and Chaco Meridian.
