SUMMARY:ABDNHA Travel Series: Romania Travelogue - Beautiful Landscapes and Complex Identities
DESCRIPTION:Speaker: Don Barrie\, ABDNHA Board Member \nJoin Geologist\, traveler\, and photographer Don Barrie for this fascinating recap of his recent trip to Romania. Last summer\, Don traveled to Romania for two weeks as a photographer for the Global Neighborhood Project\, a San Diego-based organization dedicated to citizen diplomacy. During the trip\, he met with students and faculty at a Hungarian-language school in Romania’s Transylvania region. He also photographed locals in a remote farming village outside Brasov\, Romania\, as they shared their stories and explained their way of life. For this informal talk\, Don will share his photographs and his overall first impressions of this land of striking beauty and rich history. In the ABDNHA Library.  General Public: $12\, Members: $10\, Volunteers: $8. Register online at abdnha.org or at the Nature Center\, 760-767-3098.

SUMMARY:Lecture: Applied Earth Science - The Rare Earth Elements
DESCRIPTION:Speaker: Madhukar (Maud) Rao\, Ph.D. \nRare earth elements have been very much in the news recently\, but what exactly are they?  What are they used for? Why are they so uniquely essential? Where do they come from? How are they processed? And\, why does the U.S. import about 80 percent of them\, despite their importance? Dr. Rao is a retired Chemical Engineer and currently serves as the Chief Strategy Officer for Workforce Development at Innovation Impact Partners\, LLC. He has more than 36 years of industrial R&D experience with major chemical and semiconductor materials companies. Maud volunteers as a math and science teacher and as a docent at the San Diego Air and Space Museum\, and enjoys engineering\, history\, and teaching. In the ABDNHA Library. General Public: $12\, Members: $10\, ABDNHA Volunteers: $8. Register at abdnha.org or the Nature Center at 760-767-3098.

SUMMARY:SPECIAL ROCK ART WEEKEND: Dr. Whitley's Lecture\, Part 1 - Understanding Native Californian Rock Art (FULL)
DESCRIPTION:Speaker: David Whitley\, Ph.D. \nThe meanings of pictographs and petroglyphs have long been a mystery to most people\, including archaeologists. The result has been a series of supposedly common-sense guesses\, like “hunting magic” or “maps to water\,” that were offered because people claimed Native Americans themselves did not know why these sites were made or how they were used. But the unpublished field notes of the state’s Native American tribes — the ethnographic record — some dating back to the 1870s\, together with extensive published research\, paint a different picture.  With substantial research to identify and compile this widely scattered information\, Dr. Whitley will explain how a clear understanding of the origins\, meanings\, and uses of the sites results\, providing a better understanding and appreciation of the remarkable artistic and intellectual record of California rock art. In the ABDNHA Library.  General Public: $12\, Members: $10\, ABDNHA Volunteers: $8. Register at abdnha.org or the Nature Center at 760-767-3098.

SUMMARY:SPECIAL ROCK ART WEEKEND: Dr. Whitley's Lecture\, Part 2 - European Cave Paintings & the Origins of Art & Religion
DESCRIPTION:Speaker: David Whitley\, Ph.D. \nFew aspects of our archaeological past are more intriguing than the ancient cave paintings and engravings of France and Spain. These are exemplified by the remarkable murals in sites such as Lascaux\, Altamira\, and Chauvet caves\, which date from roughly 14\,000 to 35\,000 years ago. They\, and similar sites\, are widely regarded as signaling both the first “creative explosion” in human history\, as indicated by the earliest true masterpieces of art\, as well as the origins of religious beliefs and practices. \nIn tonight’s presentation\, Dr. Whitley will discuss his extensive research into cave art and how he has brought two distinct sciences together to find answers.  The first part begins with archaeological data that suggest when\, where\, and why this phenomenon may have first emerged in human history. The second part involves investigating the cognitive sciences to understand why religious beliefs are found in every culture\, at all time periods. This is not to determine the veracity of religious belief\, which is a matter of personal faith\, but to explain why religious and spiritual beliefs are universal to the human experience. Whether it is the result of biology or divine inspiration\, aspects of human cognition have caused us to believe in gods\, spirits\, and spirit worlds from the earliest days of humanity.

SUMMARY:Lecture: Mojave Desert Tortoises
DESCRIPTION:Speaker: Melissa Merrick\, Ph.D\, Researcher\, San Diego Zoo and Wildlife Alliance\nDr. Merrick will present an update of her presentation last year about her research of the Desert Tortoise Recovery Program at the San Diego Zoo Wildlife Alliance\, highlighting a partnership with The Living Desert Zoo to raise larger\, less vulnerable juvenile tortoises for release.

SUMMARY:Lecture: Beauty of the Universe - The Astrophotography of Michael Scott Poirier
DESCRIPTION:Speaker: Michael Poirier \nMichael Poirier’s presentation will include many images of galaxies\, nebulae\, planets\, and other celestial objects taken from his observatory in Borrego Springs and other locations in Southern California. He will also give a brief explanation on how he captures and processes these images. \nMichael says he still doesn’t know what he wants to be when he grows up. Educated in the U.S. and Switzerland\, he served as a commissioned officer in the United States Navy before embarking on a successful career as a biotech executive and entrepreneur. Through it all\, he has always been interested in astronomy.  “My interest in astronomy began when I was a teenager. One night\, I looked up at the stars through binoculars and noticed that one was a large\, fuzzy blob. Later\, I found out that it was the Andromeda Galaxy. Ever since then\, I have become passionate about it and have focused on astrophotography.”  GP $12\, M $10\, V $8.

SUMMARY:Lecture: Native American Life\, Use of Native Plants
DESCRIPTION:Speaker: Cathy Chambers\, Volunteer\nMany hundreds of years ago\, there was nothing close to a store in all of North America. The people living here before that time needed materials for clothing\, storage containers\, food\, tools\, and other essentials to build living structures. All of these materials were gathered and processed into the items they needed. Groups traded with each other for what they needed\, offering what they had in surplus in exchange. In this presentation\, you will see and handle samples of plants and the objects made from them that were used in everyday life in the surrounding desert. Cathy Chambers is a lifelong naturalist who studied ethnobotany for her personal and professional development\, starting her career decades ago here in Anza-Borrego. GP $12\, M $10\, V $8.

SUMMARY:ABDNHA Desert Lecture Series: Pursued by a Mountain Lion
DESCRIPTION:Speaker: James W. Cornett\, Desert Ecologist\, Author\nWhile hiking alone in the Baboquivari Mountains of southern Arizona\, Jim Cornett came face to face with a mountain lion that had stalked him down a mountainside. The confrontation lasted nearly forty-five minutes\, with the cougar lunging at Jim several times\, in an attempt to get him to turn and run. Join Jim as he recounts the frightening experience and explains what he did right and what he did wrong in his encounter with the largest of resident American felines. Along the way\, Jim will describe the natural history of mountain lions\, the threat they pose to humans (real and imagined)\, and their future in an increasingly urban world. Free for ABDNHA members\, all others $10 at the door of the Performing Arts Center. Seating is first-come\, first-served.
