Donna Gillette received a Ph.D. in Anthropology/Archaeology, from the University of California, Berkeley. Her dissertation research involved the placement of cultural markings (rock art) on the landscape in Northern California and a survey of other pre-historic activities in the area and determining if there was a temporal connection. With a life-long interest in rock art and the southwest, she returned to school for graduate studies after her children were grown. Since completing her studies, she has worked at consulting, and donated her expertise to the Dana Adobe, a Mexican Land Grant, in California, where she also completed a NAGPRA project. In addition to rock art, her research interests include California archaeology and Indigenous communities, landscape archaeology, historic archaeology, Mission studies and Ranchos. She has developed a deep interest in defining the sacred, especially from the Native perspective. Gillette recently served as lead editor on a volume on Rock Art and Sacred Landscapes (Springer 2014). She has also presented papers at multiple conferences (including International) and published in their Proceedings. Additional articles have included a contribution to Archaeology in America: an Encyclopedia. Dr. Gillette has served on the Board of several non-profit archaeological associations. Sanders was employed at museums for 35 years. From 1998 until 2016, he was the site manager at the Minnesota Historical Society’s Jeffers Petroglyph Historic Site. With the guidance and participation of members from the Arapaho, Cheyenne, Dakota, Lakota, Shoshoni, and Anishinaabe communities, he developed research, educational, and preservation programs at Jeffers Petroglyphs. Sanders has worked with Dakota elders to record and preserve cultural histories, traditional parables, and interpretations of the carvings and cultural sites along the Red Rock Ridge. As a practitioner of Indigenous-centered archaeology, he is employed as an Indigenous Archaeological Specialist at Hamline University. He has been a principal investigator along with Brian Hoffman on archaeological surveys for over 1400 acres along the Red Rock Ridge. Tom is the Director of the Red Rock Ridge Research Group made up of Dakota elders and archaeologists. The group’s primary goal is to preserve Indigenous cultural sites along the Red Rock Ridge. He is a member-at-large of the Minnesota State Historic Preservation Review Board. He is descended from both parents from Cherokee ancestors. However, he is not an enrolled tribal member, makes no claim of Cherokee cultural knowledge, and does not speak for the Cherokee Nation or their way of knowing and being.
