Petroglyphs in Arizona courting again hundreds of years will quickly be digitised and reinterpreted with assist from native Indigenous teams. On the Deer Valley Petroglyph Protect, a 47-acre website in Phoenix, round 1,500 symbols created between 500 and 5,000 years in the past have been recorded. The location’s petroglyphs have been final inventoried in 1980 utilizing now-antiquated strategies, and archaeologists imagine that extra motifs could possibly be found. They may work with 4 regional tribes—the Salt River Pima-Maricopa, Gila River, Tohono O’odham and Ak-Chin—to create an up to date database.
An archaeological survey of the location was first carried out previous to the development of a collection of dams within the space within the late Nineteen Seventies, which have been supposed to guard new residential developments from flooding and monsoons. The archaeologist J. Simon Bruder of the Museum of Northern Arizona in Flagstaff was contracted by the US Military Corps of Engineers for the venture, engaged on website for round a month and compiling one of many first intensive quantitative reviews of petroglyphs within the state.
Bruder linked the location primarily to the Hohokam and Patayan, precolonial cultures that when resided all through Arizona. A subsequent evaluation in 1994 discovered that the location was a lot older than Bruder thought, and that it had been used over millennia as a buying and selling centre. One of many oldest recognized rock peckings there exhibits an atlatl—a prehistoric weapon that was seemingly exchanged there throughout the Archaic interval. Atlatls have been outmoded by the bow and arrow; their presence usually serves as a benchmark for courting archaeological websites.

The Deer Valley Petroglyph Protect was listed on the Nationwide Register of Historic Locations in 1984. A museum housing artefacts unearthed within the space—like ceramic and stone fragments, shells and cobble hammerstones—opened in 1994.
“We need to get up to date info, like geolocation factors and pictures and sketches, so we are able to higher perceive which communities and traditions have been current right here,” John Bello, the assistant director of the protect, tells The Artwork Newspaper. “As a result of petroglyphs are uncovered to the pure components and there aren’t conservation strategies for preserving them, these symbols will finally be lined by the desert varnish.”
Battling in opposition to ongoing vandalism
Along with issues over the eventual pure erasure of the motifs, the venture responds to ongoing vandalism at archaeological websites. When the unique survey was carried out, researchers discovered that a number of petroglyphs had been used for goal follow; some boulders have been marked with bullet holes. A fence was constructed for cover, though the location has nonetheless suffered defacement, such because the carving of initials and dates into its rocks.
The archaeologist Aaron Wright of the non-profit Archaeology Southwest is spearheading the digitisation venture with a group of three researchers, together with two college students and the archaeologist Charles Arrow, a Fort Yuma Quechan tribal member. The work is predicted to take round 4 weeks starting this month, relying on whether or not extra motifs are discovered and the size of session with the tribes.
The tribes’ position is to help in decoding the motifs and reviewing and approving the symbols which can be photographed or sketched for the digital database. Motifs of non secular or religious significance that shouldn’t be out there to a wider public shall be protected. An overarching goal of reprising the analysis is to be extra inclusive of the tribal communities that weren’t approached to take part within the unique evaluation of the location.
On the subject of the cultural significance, we now have to defer to the tribes

“It’s a collaborative endeavour,” Wright says. “These communities don’t essentially have the capability to help with the fieldwork, however we wish their help in contextualising the heritage property. Our ability set is the fieldwork and administration ingredient, however in terms of the cultural significance, we now have to defer to the tribes.”
The archaeological group has met with tribal historic-preservation officers and cultural-resource administrators from the varied communities and can proceed to take action all through the venture, working to create further academic supplies and professional-development instruments to enhance the database.
“The multiculturalism of the location is clear within the iconography,” Wright says. “There are cultural influences from a number of ethnohistoric tribes and linguistic teams. The unique report interpreted the overwhelming majority of the imagery as related to the Hohokam, as a result of there was a Hohokam settlement there. Since then, we now have recognised extra of the Archaic dimension, and can have the ability to assess that additional as soon as we now have up to date information.”
Wright provides that the primary evaluation used methodologies that have been groundbreaking for that period—resembling a “panorama scale method”, which considers how prehistoric communities constructed and utilised the setting round them. “We could have totally different views on what was interpreted by way of the location’s significance and function, however the report was progressive for its time and continues to be instrumental for our work,” he says.
Treacherous and demanding website
Challenges for the venture embody working whereas the location is open to the general public, which might be distracting for researchers, and gaining bodily entry to among the motifs. “The location is fairly treacherous and bodily demanding, since there are common places the place imagery is concentrated alongside the bottom of the escarpment however others are close to the highest and never seen from any considerable distance,” Wright says. “An unanticipated problem can be if there are considerably extra petroglyphs than initially evaluated.”
The Deer Valley Petroglyph Protect stays little recognized regardless of its scale and significance as a cultural heritage website—in contrast to standard vacationer sights just like the Painted Rock Petroglyph Website round 100 miles to the south-west. Earlier than the Covid-19 pandemic, the protect acquired someplace between 5,000 and eight,000 guests per 12 months, however numbers plummeted within the years that adopted. Now it has regained some floor. Round 5,000 individuals visited final 12 months, and organisers estimate that round 6,000 will go this 12 months.
“The location has many petroglyphs, nevertheless it’s nonetheless within the spectrum of reasonable by way of density and abundance,” Wright says. “Nonetheless, it shouldn’t be under-emphasised.”
