“Dstretch Technology Leads to the Discovery of New Rock Art in Poway and Rancho Bernardo"

Dr. Greg Erickson
Dr. Greg Erickson received his Ph.D. in Biology at the University of California, San Diego. After completing postdoctoral training at Harvard Medical School, he joined the faculty in the Department of Reproductive Medicine at UCSD. He is a member of the American Rock Art Research Association, a docent at the Kumeyaay-Ipai Interpretive Center in Poway, and President of the San Diego Rock Art Association. Since retirement, he has pursued his passion for rock art, using state of the art DStretch enhancement technology to discover new rock art in Rancho Bernardo, Poway, and Escondido. 

The Native Americans that lived along Green Valley Creek in Rancho Bernardo and Poway produced quite extraordinary rock art. The style, named the Rancho Bernardo Style (RBS) by Ken Hedges, is unique and not found anywhere else in North America. Since its discovery almost a century ago, this rock art remains highly weathered and almost impossible to visualize with the naked eye. As such the vast majority have remained either unrecognized of recognized at a poorly defined level. Recently, a new state-of-the-art technology, termed DStretch, has overcome this barrier and enabled visualization of previously invisible images. Using DStretch, Dr. Erickson has discovered a stunning array of new one-of-a-kind RBS motifs that are both fascinating and important to expanding our understanding of RBS rock art. In this lecture, he will provide an overview of the rock art found along the Green Valley Creek with emphasis on the new discoveries afforded by DStretch.

   The VCAS/Ventura County Archaeological Society was established in 1972 when concerned Ventura County citizens as well as local professional and avocational archaeologists saw a need to organize, study and preserve our County's rich prehistoric heritage.

  The Society has been instrumental in the implementation of research and preservation goals aimed at our local archaeological resources.  With an eye towards the future the Society has a collections and archival curation program, site recordation and monitoring program, and a continuing education program. 

From the 101 Freeway, take the Ventu Park Road exit, south to Lynn Road. Head west to Susan Drive and turn right in to the parking lot.
