Tucson Prehistoric Human Bones Unearthed During Downtown Construction Project; Excavation Suspended
TUCSON, AZ — A routine construction project in downtown Tucson has been halted after workers uncovered prehistoric human bones at a depth of approximately 12 feet, local authorities confirmed Monday. The discovery occurred at the site of a new commercial development near the intersection of Congress Street and Church Avenue prompting immediate suspension of all excavation activities. Officials from the Arizona State Museum and the Pima County Office of the Medical Examiner responded to the scene, identifying the remains as prehistoric in origin based on soil context and bone mineral composition. According to project supervisor Maria Delgado, the bones were found alongside fragmented pottery and stone tools, suggesting the site may hold archaeological significance. The Tucson City Council has been notified, and a full archaeological review is underway to determine the age and cultural affiliation of the remains. A spokesperson for the Arizona State Museum stated that the discovery underscores the region's deep indigenous history, noting that the Tucson basin has been inhabited for thousands of years. Construction crews have been reassigned pending further investigation, with no timeline given for when work may resume. Authorities urge the public to avoid the area until the site is secured.
