Ancient Archaeological Sites
Prehistoric Cultural Sites Within the Proposed Project Area
The lands proposed for the Camino Madre wind project contain physical evidence of long-term prehistoric human occupation. Archaeologists and local residents have documented over 160 dwelling ruins in the area, including what appear to be traditional pit-house structures and multiple collapsed Ancestral Puebloan masonry structures surrounded by pottery and artifacts.
These sites typically feature:
Rectangular arrangements of lined stones marking the outlines of semi-subterranean pit houses.
Scattered pottery sherds across the surface.
One documented structure shows evidence of taller walls (originally at least 6 feet high) that have collapsed both outward and inward, consistent with the weathering of mud mortar over centuries.
Associated artifacts include hundreds of pottery sherds dispersed up to 100 feet from the structure, chert tool fragments, broken arrowheads, and broken metates (grinding stones).
The location of the more substantial structure - on a gentle hill spur where two major animal migration or herd valleys converge - is a classic setting for prehistoric habitation sites, offering access to water, game, plant resources, and defensible high ground.
This is one of several ancient ruins located in the heart of the wind farm project area.
Being a larger structure, it is approximately 16x20 ft and has collapsed walls spanning 6-8 ft way from rectangle base. Pottery and artifacts are scattered inside ruin and concentrated within in a 200ft radius.
Likely Cultural Affiliations
Northern Arizona, including the Yavapai County region near Seligman, was occupied for thousands of years by various prehistoric groups. The architecture and artifact assemblages observed are consistent with cultures known in the broader area:
Sinagua Culture (prominent in north-central Arizona, ~500–1425 CE): Early Sinagua communities commonly built pit houses — semi-subterranean dwellings with stone-lined walls and brush/earth roofs. Over time, many groups transitioned to above-ground masonry pueblos using local stone and clay mortar. Sites such as Wupatki National Monument (northeast of Flagstaff) showcase larger multi-room Sinagua pueblos with similar construction techniques. The collapsed taller structure and abundant pottery/tools described fit within the range of Sinagua or Sinagua-influenced sites.
Prescott Culture (specific to west-central Arizona/Yavapai County area): This regional tradition featured both pit houses and later masonry pueblos. Sites in Yavapai County often show a mix of pit-house villages and more substantial stone structures, sometimes with influences from neighboring groups.
Possible connections to broader Ancestral Puebloan traditions are also present in northern Arizona through trade, migration, and cultural exchange, particularly after major events like the eruption of Sunset Crater (~1064 CE), which influenced settlement patterns across the region.
The presence of metates, abundant pottery, and tool-making debris indicates sustained residential use, likely involving farming, hunting, and gathering. These sites represent important archaeological resources that can provide valuable information about prehistoric lifeways, trade networks, and adaptation to the high-desert environment.
Professional archaeological survey and evaluation are warranted to properly document, date, and interpret these sites. Surface finds alone cannot confirm exact cultural affiliation or age without systematic excavation and analysis.
Potential Impacts from Heavy Construction
Utility-scale development involving hundreds of workers, heavy equipment (cranes, graders, concrete trucks, turbine component haulers), and extensive road building poses significant risks to fragile archaeological sites:
Vibration and ground disturbance from heavy machinery can cause further collapse of standing or partially collapsed walls and disturb subsurface features.
Road widening or new access routes can directly destroy or bury sites.
Increased vehicle traffic and human presence during construction can lead to inadvertent damage, artifact displacement, or looting.
Long-term operational access roads may permanently alter the setting and increase the risk of unauthorized visitation or vandalism.
Cultural resources are non-renewable. Once disturbed or destroyed, the scientific and cultural information they contain is lost forever. Standard best practices for energy projects in archaeologically sensitive areas include pre-construction surveys by qualified professionals, avoidance or mitigation plans, and consultation with appropriate tribal historic preservation offices and the Arizona State Historic Preservation Office.
These sites are part of the deep human history of this landscape. Their protection and study deserve careful consideration during any development planning process.
