Tucson Prehistoric Human Bones Discovery Prompts Archaeological Investigation
TUCSON, Ariz. — A construction crew unearthed a collection of prehistoric human bones during a routine excavation at a residential development site in northwest Tucson on Tuesday, prompting a halt to all construction and the initiation of a comprehensive archaeological investigation.
What: The discovery involves multiple skeletal remains identified as prehistoric human bones, which are believed to be centuries or millennia old. Authorities have ruled out any modern criminal activity, with the Pima County Sheriff's Department deferring investigation to cultural heritage experts.
When: The bones were uncovered at approximately 10:45 a.m. local time on Tuesday, during the digging of a foundation for a new housing unit.
Where: The excavation site is located in the area of West River Road and North Silverbell Road, a region known for its historical significance as a former settlement area for ancient Indigenous populations.
Who: The discovery was reported by the construction supervisor, who immediately contacted the Arizona State Historic Preservation Office. Archaeologists from the University of Arizona and representatives from the Tohono O'odham Nation have been dispatched to the site.
Why: The bones appear to be remnants of a pre-Columbian burial ground, likely linked to the Hohokam culture, which flourished in the Sonoran Desert from approximately 300 to 1450 CE. Officials emphasize that the find complies with the Native American Graves Protection and Repatriation Act, mandating respectful handling and potential repatriation.
How: The construction team alerted authorities upon noticing bone fragments embedded in the soil. A 200-foot perimeter has been cordoned off, with geophysical surveys planned to determine the full extent of the burial site before any further development resumes.
