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 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. Mr. Jespersen has co-written and presented two papers that were published in the San Diego Rock Art Association’s Rock Art Papers, Volume 19: “Comparison of Two Sites Found in the Palen-McCoy Wilderness” (Martín R. Jespersen, Mary G. Jespersen, and George Kline) and “An Overview of Prehistoric Sites Rediscovered and Located in the Indian Pass Wilderness” (Mary G. Jespersen, Martín R. Jespersen, and Michael Savala).


George Kline was born and raised in the suburban Los Angeles area. After graduating from Bell High School, he enlisted in the Navy and served at sea in the western Pacific and Indian Oceans during the Viet Nam War. After his military service, George worked in the shipbuilding industry as a marine electrician. During that career and while raising a family, he attended community college with a fascination for the sciences. There, after taking a course in archaeology, he was hooked. In 1990 George took on seasonal work as an Archaeological Technician for the Forest Service in Modoc County. He realized he needed to complete his college degree to move up in the profession that had now repeatedly captured his imagination. After earning his BA in 2005, he continued on with studies at SDSU while employed as a business anthropologist for General Dynamics NASSCO. He earned his master’s degree in anthropology with a focus on archaeology in 2008. He retired early from General Dynamics and went to work for the San Bernardino National Forest as an archaeologist. In 2010 he accepted a position with the Bureau of Land Management (BLM) at the Palm Springs, South Coast Field Office, where he has now found a home. He manages the archaeology for 1.4 million acres of public land in five counties, on projects including several utility-scale solar power generation facilities, electrical transmission lines, and recreation facilities. He assists in fire fuels reduction, fire suppression, and rehabilitation; with minerals and mining objectives; and law enforcement in violations analyses. He is also actively involved with site protection and preservation, working with volunteers in the California Archaeological Site Stewardship Program (CASSP).
