Board of Directors

Vaughn Hadenfeldt, President

Vaughn-ProfileFrom Colorado mountaineering store owner and climbing guide, Vaughn took his love of the outdoors – and his wife and daughter – to Utah and turned his passion for the archaeologically rich desert into life as a world renowned guide in southeastern Utah. As owner and guide of Far Out ExpeditionS® he shares his knowledge of the cultural and natural histories of the landscape with visitors from all corners of the globe while emphasizing the ethics and understanding of exploring those sites.

Vaughn’s early work and interest in high altitude archaeology as an anthropology major at Colorado State University, later developed into his total commitment to southwest archaeology – specifically in the Cedar Mesa region. He has worked with leading local archaeologists on documentation and excavation projects throughout the area. Notable projects include the Weatherill Grand Gulch Research Project, Earthwatch/BLM Basketmaker Rock Art Documentation Project and many times as part of the Ababjo Archaeology crew.

It is his fascination and appreciation for this region that has propelled him to his place as President of Friends of Cedars Mesa. Vaughn strives to emphasize the importance of protecting Cedar Mesa and the surrounding area to preserve the prehistory it showcases as well as the scenic wonder it displays. Together with his understanding of the archaeology and his enthusiasm for sharing it, Vaughn incorporates a sense of place into everything he does.

Wanda Raschkow, Statewide Site Steward Coordinator

Wanda is originally from Montana. While living in Montana, she made yearly visits to Cedar Mesa and fell in love with this area. Watching the sun rise on the bluffs has been surreal- it’s hard for her to believe she now lives in Bluff.

Her first job in archeology was with the Sanpete Ranger District on the Manti-La Sal Forest. She has also worked in Montana, Wyoming, and California with the Forest Service, BLM, and Park Service.

Wanda’s experience with site stewardship includes working with the California and Nevada Site Stewardship programs- training and mentoring stewards for the Palm Springs BLM, Joshua Tree National Park, and Death Valley National Park. She has helped conduct advanced trainings in site recordation techniques and developed educational materials for stewardship trainings. Wanda taught field skills at the Bureau of Land Management’s National Training Center and for several archeology field schools.

Wanda believes public outreach and education are critical to protecting our heritage. Site stewards are an important part of reaching the public: they often interact with visitors at archeological sites and become ambassadors for the resources. This is in addition to their fundamental role of keeping an eye on the sites and documenting damage- whether natural or human-caused.

“Site stewards are great people- enthusiastic and committed, eager to learn more about archeology and to share that knowledge with others. I am looking forward to working with stewards and agency archeologists to develop a site stewardship program for Utah.”
