SUMMARY:Beginning Birding: Borrego Springs Resort (Easy) - FULL (waitlist)
DESCRIPTION:Leaders: Tom Keffer and Lee Christie\, ABDNHA Volunteers \nIf you can’t tell a sparrow from a flycatcher from a wren\, this trip is for you! Instead of racking up species\, we will slow down and take more time with each individual bird\, learning how to identify them. We will be carrying a scope\, so you’ll get a good look at what distinguishes a bird. 1.5 miles\, no elevation gain\, easy trail. Meet in the ABDNHA parking lot by 8:50 am.  Bring snacks\, binoculars\, and water. Call 760-767-3098 to reserve. Limit: 10.

SUMMARY:Lecture: Life in the Borderlands - the History of Crossing the California-Mexico Border
DESCRIPTION:Desert Lecture Series \nSpeaker: Immigration Historian Deborah Kang\, Ph.D. \nIn 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 for this lecture 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.

SUMMARY:Lecture: The Story of the Salton Sea - FULL
DESCRIPTION:THIS PROGRAM IS FULL. \nSpeaker: Dave Blanchet\, (ret.) Hydrologist \nFirst 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.

SUMMARY:Hike: Hornblende Canyon (Moderate) - FULL (waitlist)
DESCRIPTION:Leader: Rachel Rench\, ABDNHA Volunteer \nMeet at the ABDNHA parking lot at 8:00 am to carpool to a parking area South of Blair Valley. Parking is limited there\, so we need to take as few cars as possible. The hike up Hornblende Canyon is fairly flat in the beginning\, but you’ll need to be able to navigate a few small dry waterfalls until we reach a 40-foot-high dry waterfall and our turnaround point. We’ll eat lunch here and then return the way we came. This hike will be limited to 15 people. Call the Nature Center to reserve.

SUMMARY:Astronomy Lecture: Fossils of the Solar System
DESCRIPTION:Speaker: Dr. Neil Farber \nJust as fossils on Earth are remnants of past life forms\, there are astronomical fossils in space dating back to the early days of the Solar System\, which may provide insights into how the Solar System and life itself originated. NASA is conducting a multitude of missions to study asteroids\, aiming to enhance our understanding of the Solar System and explore ways to mitigate the threats posed by potential collisions with Earth. General Public: $12\, Members: $10\, Volunteers: $8. You can register online at www.abdnhaorg or at the Nature Center\, 760-767-3098. Held in the ABDNHA Library.
