Join us for this interview-format presentation. The book is a lot of fun to read, with graphic illustrations done by his niece, Lily Almeida, based in London. Signed copies of the book will be available for purchase at the end of the presentation at the reception. Location: The ABDNHA Library. General Public: $12, Members: $10, Volunteers: $8.

Lecture: Life in the Borderlands – the History of Crossing the California-Mexico Border
Borrego Springs Performing Arts Center 590 Palm Canyon Drive, Borrego Springs, CA, United StatesDesert Lecture Series
Speaker: Immigration Historian Deborah Kang, Ph.D.
In the early 1900s, people freely crossed back and forth between California and Mexico because federal immigration laws were not strongly enforced, and the two sides were often regarded as parts of the same community. World War I and the Mexican Revolution led to this change, as strict regulations were imposed amid growing concerns about foreign enemies and immigrants. Residents in the borderlands strongly objected because they relied upon easy crossings for their society, family ties, and economy. Their objections led to enforcement being relaxed once again. Our speaker tonight, Deborah Kang, is an immigration historian who will explain the evolution of laws and practices along the California-Mexico border, from around 1900 to the present day. Join us at the Borrego Springs Performing Arts Center. The program is free for ABDNHA members, and $10 at the door for the general public. Seating is first-come, first-served.

Lecture: The Story of the Salton Sea
ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United StatesSpeaker: Dave Blanchet, (ret.) Hydrologist
First there was the geology, and then came the flood. The Salton Sea is located along the San Andreas Fault, and it is geology that repeatedly created and drained a vast natural lake over millions of years, called Lake Cahuilla, in what is now the Imperial Valley. Starting in the 20th century, agriculture began to flourish in California’s Imperial Valley, and diversion canals were dug to divert water from the Colorado River into the dry desert. But the wild nature of the Colorado River soon took the upper hand. Events went horribly awry as record-breaking floodwaters destroyed the manmade dams and canals, and the full flow of the Colorado River flowed unabated into the Salton Trough for two years. Only through immense effort was the flooding finally stopped, and the Colorado River returned to its course, flowing into the Sea of Cortez. Tonight’s speaker, Dave Blanchet, is a retired hydrologist from Anchorage, Alaska, and a lifetime member of ABDNHA. General Public: $12, Members: $10, Volunteers: $8. Please register at www.abdnha.org or at the Nature Center, 760-767-3098.

Lecture: Flash Floods in Semi-Arid Landscapes
ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United StatesSpecial Earth Sciences Weekend
Speaker: Suzanne Walther, Ph.D., University of San Diego
It has been said that the two most common ways to die in the desert are from thirst and from drowning. Flash floods are the leading weather-related cause of death in the U.S. and many parts of the world, and cause billions of dollars in damage. Dr. Suzanne Walther is a fluvial geomorphologist. She studies rivers, streams, floods, sediment movement, and how the natural flow of water shapes the landscape, interacts with ecosystems, and significantly impacts human development. The focus tonight is on flash floods in semi-arid areas, such as Borrego Springs, where they can occur, the conditions that lead to their formation, the powerful forces they unleash, their effects on water supply and drought, and what can be done to mitigate their destructive impact on human development. In the ABDNHA Library. General Public: $12, Members: $10, Volunteers: $8. You can register online at abdnha.org or at the Nature Center, 760-767-3098.

SPECIAL ROCK ART WEEKEND: Dr. Whitley’s Lecture, Part 1 – Understanding Native Californian Rock Art
ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United StatesSpeaker: David Whitley, Ph.D.
The 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.

SPECIAL ROCK ART WEEKEND: Dr. Whitley’s Lecture, Part 2 – European Cave Paintings and the Origins of Art and Religion
ABDNHA Library 652 Palm Canyon Drive, Borrego Springs, CA, United StatesSpeaker: David Whitley, Ph.D.
Few 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.
In 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. In the ABDNHA Library. General Public: $12, Members: $10, ABDNHA Volunteers: $8. Register at abdnha.org or the Nature Center at 760-767-3098.

Hike: Borrego Badlands – East Truckhaven Lollipop (Moderate)
ABDNHA Parking Lot 652 Palm Canyon Drive, Borrego Springs, CA, United StatesLeaders: Sanjiv Nanda and Alan Parks
We will take the east fork of Truckhaven Wash. At about three-quarters of a mile, we will come to a boulder blockage that we will crawl our way through.

On the way back, we will climb out of Arroyo Salado and visit the Elephant, a Native American solstice site. Here, you will have an opportunity to scale some of the iconic uplifted slanting Truckhaven Rocks. We complete the lollipop by returning via the east fork of Truckhaven. This six-mile hike is rated moderate, with one place where you will have to get down on your hands and knees. Bring water, snacks, and lunch. Meet at 8:00 am at the ABDNHA Nature Center. We will carpool to the trailhead, as parking on the shoulder at Truckhaven Wash is limited. Max: 22. No charge, call or stop by to reserve, 760-767-3098.
