Collection Overview

The DAHA Digital Archive currently contains over 1,200 digital datasets, documents, reports and images focused on the ancient Huhugam (1500 B.C. – 1450 A.D.) of the southwestern U.S. These files are primarily “grey literature,” that is, unpublished reports and data sets that would otherwise be difficult to obtain. The large volume of published literature on Huhugam archaeology is not the focus of this collection.
“Hohokam” is a term first used in Frank Russell’s 1908 report that employed a now‐obsolete orthography to record Akimel O’odham (Pima) words. Many people, including many Pima and Tohono O’odham authors, now prefer the term “Huhugam,” adopting the 1970 Alvarez and Hale orthography favored by Huhugam descendant communities. As stated by Archaeology Southwest,

“Hohokam is the name of an archaeological culture. It refers to people who lived in parts of central and southern Arizona between A.D. 450 and 1450. Hohokam is not the same as Huhugam. Huhugam is an O’odham word for all O’odham ancestors, including those known to archaeologists as the Hohokam.”

The Hohokam Millennium, edited by Suzanne K Fish and Paul R Fish, 2008, published by the School for Advanced Research Press, Santa Fe.
In 2017 Arizona State University’s Center for Digital Antiquity, in collaboration with the Amerind Museum, received a grant from the National Endowment for the Humanities to create a comprehensive digital library of data and reports on archaeological investigations of the ancient Huhugam (Hohokam) in Arizona. The goal is to facilitate the discovery, access, preservation and analysis of data related to important questions in Huhugam archaeology and to support synthetic research on a variety of significant topics.
The bulk of the NEH grant-funded work on the DAHA Library began during the summer, 2017 and continued through spring, 2021.
The NEH grant that funded the creation of the DAHA collection is now complete. However, we welcome additional uploads to tDAR of reports and data on Huhugam archaeology. If you have uploaded files relevant to this collection to tDAR, please contact us so that we may include the file in this collection.
The ASU Center for Digital Antiquity worked with a number of important partners and contributors on the DAHA Library, including:
  • Amerind Foundation,
  • Bureau of Reclamation, Phoenix Area Office,
  • City of Phoenix, Pueblo Grande Museum,
  • Desert Archaeology,
  • SRI (Statistical Research, Inc.),
  • SWCA

Find Data – Explore

Ideas for searching the collection include:
  • Searching by Site Name or Site Number
  • Using the map to draw a box around an area of interest; this will return all of the results related to that geographic area
  • DAHA metadata includes archaeological temporal and cultural terms (e.g., phases, periods)
  • Using common terms for smaller geographic subareas (e.g., Phoenix Basin, Tucson Basin) or watershed names (e.g., Lower Verde River, Santa Cruz River)
  • Searching within the DAHA Collection will provide results that are focused only on Huhugam resources.
  • Searching all of tDAR will integrate documents and results from other collections that contain that same search term; while this can be helpful, it could also point to files that are only tangentially relevant. For example, searching for “turquoise” in all of tDAR will return results that include both DAHA files and non-Huhugam files.
To search only within the DAHA Collection, go to the main DAHA Collection page, enter your search term in the search box, and check the box "Search within this collection".Restricting your search to the DAHA Collection
The resources that have been added to this collection include both Hohokam and Huhugam keywords. If you search all of tDAR using one or the other you will still be able to obtain records that only list one of these keywords as both terms are synonymous in tDAR.
While most of the files are documents, the DAHA also contains data sets and images.
All documents in DAHA have been OCR’ed so the full text can be searched; however, the accuracy of the OCR varies with the quality of the printing on the original document that was scanned.

Download Files

Logging into your tDAR account gives you the ability to download files and request access or contact resource owners. Registering for an account is free and simple.
Yes. There are over 250 data sets in the DAHA Archive, primarily from the Roosevelt Platform Mound Study and Pueblo Grande.
No. Access to the material in tDAR is free of charge.
You can preview data sets and images in tDAR; to view a document you must download the file.
All files in tDAR are covered by a Creative Commons CC0 license which means the information is in the public domain. Anyone may reuse this material for any purpose without restriction. To find out more, see our Contributors Agreement.
It is a ‘best practice” to cite the source of data or documents you use. This gives credit to the document’s author(s) and lets others who read your work locate the original source material. When you download a document from tDAR we add a cover page that contains the proper citation information for that document. You can also find a citation as part of the metadata on the resource page.

Access

If a file is confidential, you can request access by using the “Request Access, Submit Correction, Comment" link found below the File Download section. This feature will allow you to send a message to the resource owner and request access. Options include: Contact, Request Access, and Suggest Correction
The most common reasons for download problems are either (a) not being logged into tDAR; or (b) the file you want is restricted. Be sure to create a (free) tDAR account and log in before trying to download a file. If a file is confidential, use the “Request Access, Submit Correction, Comment”.

Confidentiality

For all files in tDAR, individual authors or contributors decide whether to make a file publicly available or confidential. For this particular collection, we have decided to mark all files that contain both site location and culturally sensitive imagery as confidential. If a file is confidential, a redacted version will also be included that is publicly available.
Yes. Digital Curators working on the DAHA project examined each file to determine if confidential Information (information about the location of an archaeological site) and/or sensitive information (information that may be culturally offensive to some individuals or groups) was present. Confidential information and some instances of sensitive information have been redacted (removed) from the file.
