At 6:30 p.m. on Wednesday, Nov. 8 Janine Hernbrode, a retired science administrator and curriculum writer, will present "Petroglyph Patterns and Bell Rocks at Ancestral O'odham Sites." Hernbrode has spent 16 years recording rock art within 30 miles of Tucson, primarily among the sacred sites of the Ancestral O’odham people.

The San Tan Chapter of the Arizona Archaeological Society invites the public to join them at the San Tan Historical Society Museum in Queen Creek tomorrow evening for a special presentation.

At 6:30 p.m. on Wednesday, Nov. 8 Janine Hernbrode, a retired science administrator and curriculum writer, will present "Petroglyph Patterns and Bell Rocks at Ancestral O'odham Sites." Hernbrode has spent 16 years recording rock art within 30 miles of Tucson, primarily among the sacred sites of the Ancestral O’odham people.

Hernbrode is an independent rock art recorder and researcher based in and working near Tucson. Wary of becoming relentless quantifiers through rock art recording, she and her research partner, Dr. Peter Boyle, worked together to collect and analyze data obtained from their recordings of Tumamoc Hill (a three-year project of the Archaeological and Historical Society and the University of Arizona), the Sutherland Wash Rock Art District (a six-year project for the Coronado National Forest), Cocoraque Butte and Cocoraque Ranch (a five-year project for the Bureau of Land Management, the Arizona Archaeological and Historical Society, and the private owner of Cocoraque Ranch).

Boyle and Hernbrode demonstrate that ethnographic and linguistic information can suggest links to both sacred landscapes and some motifs found in rock art. Hernbrode is the leader of the Rock Band, a group of volunteer rock art recorders whose work was honored by the State Historic Preservation Office. Hernbrode and the Rock Band currently are working to inventory and record the rock art in the Tucson Mountain District of Saguaro National Park as part of an effort to understand the variety of sites in a portion of the Avra Valley.

The San Tan Historical Society Museum is located in Queen Creek at 20425 S. Old Ellsworth Road.
