  • Lecture: “I May Still Be Speaking” – Indigenous Oral Tradition of Northern Baja California

    ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United States

    Speaker: Michael Wilken-Robertson, Anthropologist
    Indigenous people of northern Baja California share ancient cultural and linguistic ties with other Yuman groups of southern California and Arizona. Over the millennia, native peoples developed richly elaborate cosmologies in which the earth, sky, plants, and animals were infused with spirit; these narratives were passed along through myths, legends, stories, and song. In this lively talk, we will hear examples of storytelling from the Kumeyaay, Paipai, and Kiliwa peoples that Wilken-Robertson has worked with for over 40 years in Baja California. The narratives will be considered in their cultural context to help us better understand the meanings embedded in them and why the particular narratives passed down for generations remain compelling to listeners today.

    Anthropologist Michael Wilken-Robertson has developed lifelong collaborative relationships with native artists and traditional authorities to foster cultural revitalization and sustainable community development in northern Baja. He has taught in the anthropology department at California State University, San Marcos. His fascination with native plants and the natural landscapes of the Californias have inspired him to explore the many ways that humans have interacted with their environments, from the ancient past to the present. Michael resides in Ensenada, Baja California, Mexico. In the ABDNHA Library. GP $12, M $10, V $8. Register online, or call us at 760-767-3098.

  • Program: The Trail Less Traveled – Baja

    ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United States

    Speaker: Alan Ehrgott

    Author Alan Ehrgott’s (The Elusive Conquest of Queen Califa) fascination with Baja started in the 1970s when he hiked the entire 1050 mile length of the peninsula, following a mix of the Camino Real, the old route established by the Spanish that led from mission to mission, as well as the far more rugged route through Baja’s mountains, where isolated ranches continue to exist today. While things are far more developed along the heavily travelled Mexico Highway 1, life in the isolated ranches have changed far less. In his presentation, Alan shows parts of his original journey, and tells the story of the natural and cultural history of Baja, including the existential conflict between native tribes, Spanish conquistadors and Jesuit Priests, and he highlights points of interest such as the UNESCO Indigenous giant rock murals in the Sierra San Francisco. In the ABDNHA library. Register online or call 760-767-3098. GP $12, M $10, V $8.

  • ABDNHA Desert Lecture Series: Bobcats in the Neighborhood

    Featured
    Borrego Springs Performing Arts Center 590 Palm Canyon Drive, Borrego Springs, CA, United States

    Speaker: Andy Blue
    Andy Blue discusses a fascinating animal, the bobcat, found both in the wild and in our semi-rural community of Borrego Springs. Although bobcats are more numerous than many realize, they are more secretive than their fellow upper-tier predator, the coyote.

    Andy has been a powerhouse in the zoological community for many years, working in Russia, Ukraine, Iraq, Cuba, Southeast Asia, and Latin America. He started at the San Diego Zoo Safari Park at age 16 and became a curator. He has served as Zoological Manager at Disney’s Animal Kingdom and as director of the Ramona Wildlife Center. Currently, he is the Campus Director at the San Diego Humane Society. The highlight of his job is returning rehabilitated animals to the wild. General Public: $10 at the door; Members: no charge. Seating is first-come, first-served.
