Dr. Patricia Martz

Advocacy for Preservation

The California Cultural Resources Preservation Alliance, Inc. (CCRPA) was formed in 1998 and incorporated as a 501 ( c ) 3 non-profit charitable organization in 2003. Its mission is to protect and preserve cultural resources including archaeological sites, historic sites, sacred sites, and traditional cultural places in southern California with a focus on Orange and Los Angeles Counties. CCRPA formed in response to accelerating development, especially in coastal California, and the continuing loss of a number of significant archaeological sites including coastal villages and cemeteries in Orange County.

Dr. Martz received her BA from California State University, Long Beach and her Ph.D. from UC Riverside. Her archaeological research focuses on the pre-contact cultures of southern California and how and why they achieved a high level of cultural complexity within a hunting and gathering economy. She has conducted archaeological investigations in California for over 40 years.


Currently she is founder and president of the California Cultural Resource Preservation Alliance (CCRPA), a nonprofit organization of archaeologists, concerned citizens, historians, and Native Americans working together to promote the protection and preservation of cultural sites. CCRPA was founded 1998 with Lillian Robles, a Juaneno/Acjachemen elder who has since passed.


Dr. Martz is Professor Emerita Department of Anthropology, California State University, Los Angeles, where she taught for 20 years. As professor of archaeology, she was Principal Investigator for the San Nicolas Island Archaeological Research Program, a grant funded research program designed to place the US Navy in compliance with Section 110 of the National Historic Preservation Act. The research program provided archaeological field training, research and publication opportunities, and jobs for students underrepresented in archaeology.


Dr. Martz served as Prehistoric Archaeologist for the State Historical Resources Commission (SHRC) for six years. During that time, she served as Chairperson of the Commission and Chairperson of the State Historical Resources Commission Curation Committee. Under her leadership, this Committee produced the State Curation Guidelines. She also was Co-Chair of the California Preservation Task Force Subcommittee on Archaeology. This committee was charged with identifying the major problems present in California archaeology, recommending solutions, and producing a final document which was published in the 1997 Comprehensive Statewide Historic Preservation Plan for California.


Dr. Martz was the first archaeologist hired by the Los Angeles District US Army Corps of Engineers (COE) and served as Senior Archaeologist for 13 years. The COE constructs flood control projects and other water related infrastructure. She started as a graduate student and was convinced that she would have to resign because her professor called the COE the “Corpse of Engineers” because they dammed all the major rivers. As an employee, she was given a stack of historic preservation laws and regulations and was told to “tell us what we need to do to be in compliance.” A major achievement was the preservation of a major rock art site and the construction of a cultural interpretive center near Phoenix, Arizona.

George Kline and Martín Jespersen

A Pristine Prehistoric Site within a Historical Site at Green Hill (CA-RIV-12608/H)

George Kline at Dos Palmas Preserve.

Dos Palmas Preserve is situated along the eastern high shoreline of ancient Lake Cahuilla. The Preserve features a complicated and rich prehistory and history from the last desiccation of the lake. The Bradshaw Trail, the stage stop, the Ranch House Adobe, and all the colorful cast of characters within have contributed to the interesting history. The BLM plans to open up the Preserve to the public for the interpretation of its history, geology, botany, and wildlife.


Martín R. Jespersen attended CSU Fullerton and National University and earned his MA is in Cross-Cultural Education. He currently works in the Santa Ana Unified School District, where he is a language and culture instructor. He volunteers with the California Archaeological Site Stewardship Program (CASSP) to support the preservation of archeological sites and creates and updates site records for various regions, including Palm Springs, Barstow, El Centro, and Needles, and works with the US Forest Service and California State Parks. Mr. Jespersen and his wife, Mary, have been mentored by George Kline and Daniel McCarthy. They have located and documented many sites in the Barstow Bureau of Land Management (BLM) region. They have worked closely with George Kline, Palm Springs BLM, on multiple projects, including the documentation of the new Palen Tank site, CA-RIV-12421; updating the CA-RIV-980 site records, originally documented by Daniel McCarthy; and documenting the new Dos Palmas site in the Coachella Valley. The Jespersens worked closely with Daniel McCarthy on the Coyote Hole project. Future studies, scheduled for spring 2019, will concentrate on the Native American trail system in the Palen-McCoy Wilderness.


George Kline earned his MA in Anthropology with a focus on archaeology in 2008. He currently is an archaeologist for the BLM at the Palm Springs, South Coast Field Office, where he manages the archaeology for 1.4 million acres of public land in five counties. He is also actively involved with site protection and preservation, working with CASSP volunteers.
