SUMMARY:Hike: West Butte (Moderately Strenuous)
DESCRIPTION:Leader: Rachel Rench\, ABDNHA Volunteer\nMeet at the ABDNHA parking lot at 8 a.m. to drive to the slot parking area.

We backtrack a bit after the summit and follow an informal trail down to Borrego Mountain Wash. We’ll follow the wash to the bottom of The Slot and climb up to the parking area to finish our outing. Expect a 5-mile hike with 700 ft of elevation gain and loss. This trip will be limited to 15 people. Call 760-767-3098 to reserve.

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:4WD Field Trip: Ancient Lake Cahuilla
DESCRIPTION:Special Earth Science Series! \nLeader: John Peterson\, Hydrologist and Geologist \nApproximately 12\,000 years ago\, the Colorado River altered its course\, forming a massive prehistoric lake known as Lake Cahuilla\, which is now the Salton Sea.   The lake served as a vital resource for the Cahuilla\, Kumeyaay\, and Cocopah peoples. Over the centuries\, the lake filled and dried up many times. It last filled between 1731 and 1733. Hydrologist John Peterson will lead a half-day field trip to the Salton Sea\, where participants can explore the ancient lake’s remnants\, including visible “bathtub rings” and fishing traps. Meet at ABDNHA at 8:15 am. General Public: $18\, Members: $12\, Volunteers: $10. Register online or at the Nature Center\, 760-767-3098. \nRegister here for the field trip.

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. You can register online or at the Nature Center\, 760-767-3098. \nRegister here for the program.

SUMMARY:Lecture: “I May Still Be Speaking” - Indigenous Oral Tradition of Northern Baja California
DESCRIPTION:Speaker: Michael Wilken-Robertson\, Anthropologist\nIndigenous 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. \nAnthropologist 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. \nRegister here for the program.
