2020 will be the  23rd and 27thyear anniversaries of  the Yucatán Geophysical Archaeological Survey Project at the Maya archaeological sites of: Chichén Itzá (1993 and 1997), Balankanche Cave (1997), Kinich Kakmo Pyramid, Izamal (1997), and Dzibilchaltún (1997).

The 1993 and 1997 Yucatán Geophysical Archaeological Survey Projects are dedicated to Alfredo Barrera Rubio, and in memory of Norberto Gonzalez Crespo, and Peter Schmidt.

A summary of each geophysical survey has been published as a PDF, and can be viewed on your browser by clicking the following link: Geophysical archaeological surveys at Chichen, and other siites in Yucatan 1993, 1997

The posted PDF project summary is to honor and thank those who worked with us in the field or otherwise supported our work in many special ways, and to bring the use of geophysical technology designed for archaeological applications to the attention of our archaeologist colleagues.

The principal investigators for the project were William A. Sauck, Professor of Geophysics, Institute for Water Sciences, Western Michigan University-Kalamazoo, and Lawrence G. Desmond, Assistant professor of anthropology/archaeology, University of Minnesota-Morris. The academic positions were as of 1993.

Santo Tomás Jalieza, Oaxaca, Mexico: An ethnographic study. 2019. San Francisco: Blurb, Inc. [Click on title above, and view the entire book by clicking on Preview.

120 pages, 83 photos. Includes maps, plans, and tables. Portrait: 10×8 inches. Available from Blurb, Inc. in paperback, hardback, and image wrap.

For this edition, the thesis manuscript in the library of the Universidad de las Américas has been edited, but the original findings have not been changed, photos were digitized, and current maps and illustrations updated. Photos selected for this book are from the Desmond Collection in the photo archive of the Peabody Museum, Harvard University.


It was during my second year of graduate studies in anthropology at the Universidad de las Américas in Cholula, Mexico that I began to plan fieldwork for my master’s thesis. I had come to the university in 1970 to study the ancient civilizations of Mesoamerica and learn archaeology, but the chairman of the department of anthropology was a cultural anthropologist, and he had other ideas for my thesis.

His plan was that I should carry out an ethnographic study of a small farming community in one of the valleys south of Oaxaca City rather than an archaeological study. So, in 1973 research began with the help of my family and the welcoming people of Santo Tomás that lasted around four months, and resulted in this ethnographic study.

The ethnography includes an accumulation of considerable descriptive material useful for gaining a basic understanding of village life, but the most important finding was that after decades of debate and compromise a weaving cooperative was established in the village. The process of founding the cooperative led to the practice of resolving social and economic conflict by discussion, debate, and compromise rather than by the violence that is said to have been endemic in the area until around the mid-20th century.

BIM for Heritage:
Developing a Historic Building Information Model

  • Authors: Sofia Antonopoulou, Dipl-Ing Arch, MSc Arch Cons, and Paul Bryan BSc, FRICS.
  • Published by Historic England July 2017.
  • THE BOOK SUMMARY quoted from the book–

This publication on Building Information Modelling for heritage (Historic BIM) offers guidance for owners, end-users and professionals in the fields of heritage and construction. By raising awareness of the potential advantages of a BIM approach, this guidance will help users successfully implement BIM in heritage projects.

Historic BIM is, by definition, a multi-disciplinary process that requires the input and collaboration of professionals with very different skillsets. It is also a fast-developing field in terms of research, official guidance, standards and professional practice. This publication addresses the issues surrounding the production and use of BIM for historic buildings, and provides information about guidance and standards available elsewhere for managing a building’s entire life cycle effectively.

The New York Public Library’s Photographer’s Identities Catalog (PIC) website PIC – Photographers’ Identities Catalog states:

“Photographers’ Identities Catalog is an experimental interface to a collection of biographical data describing photographers, studios, manufacturers, and others involved in the production of photographic images. Consisting of names, nationalities, dates, locations and more, PIC is a vast and growing resource for the historian, student, genealogist, or any lover of photography’s history. The information has been culled from trusted biographical dictionaries, catalogs and databases, and from extensive original research by NYPL Photography Collection staff.”

Some problems with the PIC entry for Alice Dixon and Augustus Le Plongeon:

As stated, the PIC relies on “trusted” information from a number of published sources, but the source about Alice Dixon and Augustus Le Plongeon, The Union List of Artist’s Names (ULAN) published online by the J. Paul Getty Trust in Los Angeles, has a number of factual errors in need of correction, and lacks bibliographic entries of substance about their photography.

Alice Dixon Le Plongeon- ULAN Full Record Display (Getty Research)

Augustus Le Plongeon- ULAN Full Record Display (Getty Research)

The biographical “Note” in the ULAN entry is used for both Alice and Augustus Le Plongeon: “British, of French origins; later lived in America. Augustus worked with his wife Alice, photographing local people and archeological sites, including St.Thomas, Tiahuanaco, and Chichén Itzá.”

An update and corrections to the ULAN biographical note:

1) Alice Dixon Le Plongeon (1851-1910) was born in London, and had no French origins. Augustus Le Plongeon (1826-1908) was born on the Island of Jersey to French parents.

2) Both Augustus and Alice were trained photographers. Alice learned photography from her father Henry Dixon, a noted London photographer, and Augustus learned photography from the English photographer Fox Talbot. He began practicing photography in the 1850s in San Francisco, California.

3) Alice Dixon and Augustus Le Plongeon first met in London in 1871, and were married in New York City before leaving for Yucatán in 1873 to carry out archaeological and photographic projects. Alice did not accompany Augustus on photographic expeditions to the island of St. Thomas in the Caribbean or Tiahuanaco, Peru in the 1860s.

4) From 1873 to 1884, the Le Plongeons photographed Maya archaeological sites, ethnographic subjects, made portraits of native peoples and colonialists, landscapes, flora and fauna, and Colonial architecture in Yucatán, Mexico, and British Honduras (Belize).

5) Recently accessed archival materials indicate Alice was behind the camera as much as Augustus, if not more, and was responsible for the processing of their wet collodion glass negatives, and prints.

6) More than 2,500 negatives and prints made by the Le Plongeons are currently archived in public institutions, and private collections.

It should be noted about two years ago the administrator of Getty’s ULAN stated they planned to correct the entry for the Le Plongeons. It was to be based on the Getty Research Institute’s short biographical entry for Alice Dixon and Augustus Le Plongeon that can be found in its Finding Aid. The update has yet to be made to the web page, so it was thought prudent to publish this post until corrections are made.

In the meanwhile, for an excellent biographical summary of the Le Plongeons’ lives and work in archaeology and photography consult the Getty Research Institute’s Finding Aid for the Alice Dixon and Augustus Le Plongeon collection of photographs and other archival materials.

Bart Anderson, journalist and computer specialist, saw the need for faster access to the data entries for the 1,037 photos in the Catalog of the 19th century photographs of Alice Dixon and Augustus Le Plongeon.

While the catalog was published as a book and PDF with an introduction that gives background about each collection, historical context, catalog organization, and other technical information Anderson noted considerable time was required to search the photo collections.

The catalog photo entries had been created as a Word document by Desmond. Anderson then took the Word file and converted it into a CSV file that is compatible with most spreadsheet and database programs, and then into an Excel file for use here. Unfortunately WordPress does not support CVS files. Email me, and I can send a copy of the file.

The Excel file is free for download, and while it retains the copyright of Lawrence G. Desmond, it is authorized for use for research purposes. The Excel file is about 300 Kb.

Catalog Organization and Materials Description

NOTE: For a complete introduction to the catalog of collections refer to the book:

Cross Reference:

X Ref: PM-P2500F


X Ref: PM-P2500F similar

The Cross Reference field gives the catalog numbers of identical or similar photos in other collections. Similar photos are defined as having the same subject matter, but they were taken at a slightly different angle or time of day from the same camera position. The differences between similar photos are often subtle and hardly noticeable at first viewing.

When the Cross Reference field does not list an identical photo in another collection that indicates that the photographic item is unique to that collection.

Note for Excel users: Under the column titled “Description” — the cell is to short to view the text for item numbers 34, 190, and 960. Excel has entered a string of ##### rather than the text. To view the texts simply double click within the cell.

Cuellar, jose

Emeritus San Francisco State University Professor José Cuellar, aka Dr. Loco, and leader of Dr. Loco’s Rockin’ Jalapeño Band.

José Cuellar, Professor Emeritus of Latina/Latino Studies at San Francisco State University, a noted saxophone player and nicknamed “Dr. Loco” because he leads the musical group called Dr. Loco’s Rockin’ Jalapeño Band, will be playing ancient ocarinas from Central and Mesoamerica at Harvard University’s Geological Lecture Hall at 6pm on March 31. Admission is free and open to the public. Better get there early!

Thanks to Professor Davíd Carrasco, director of the Moses Mesoamerican Archive and Research Project at Harvard, and Harvard University’s Peabody Museum, “Dr. Loco” will be playing a variety of ocarinas made by the ancient peoples of Mesoamerica and Central America. They were discovered by archaeologists who call them “artifacts,” but for Professor Cuellar they are wonderful musical instruments.

Performance: Dr. Loco will be playing the ocarinas at the Geological Lecture Hall, 24 Oxford Street, Cambridge, Massachusetts on March 31 at 6pm. The performance is free and open to the public.

For additional details, here is the link to the Peabody Museum’s web announcement of the performance, and a museum exhibit of the ocarinas. Reviving the Ancient Sounds of Mesoamerican Ocarinas | Peabody Museum

I agree, this has little or nothing to do with archaeology, but I wanted to share an amusing moment as we drove through a downpour, windshield wipers on full blast, on the way to SFO a couple days ago. Give us more…
