Asteroid Impacts on Earth
Speaker: David K. Lynch, Ph.D.
Asteroids and meteoroids strike the Earth every day, but most are too small to survive passage through the atmosphere. Only those larger than a few tens of meters across can reach the ground, and these are rare. The last one was in 1908 near Tunguska, Russia, when an asteroid or comet nucleus caused a10 megaton airburst that flattened trees in an area larger than Washington D.C. About 60 million years ago an object estimated to be 6 miles across struck the Yucatan area of Mexico. The billion megaton explosion created a 110-mile wide crater and is thought to have been the cause of the Cretaceous-Tertiary Mass Extinction that killed most higher-life forms including the dinosaurs. What are the chances of getting hit by a civilization-disrupting asteroid? Who is in charge of protecting the Earth from asteroids? Come to the talk and find out! NM $12; M $10; V $8. In the ABDNHA Library.

Desert Lecture Series The Colorado River: From the Glaciers to the Gulf
Speaker: Jim Turner
Jim Turner is an historian, author, and public speaker from Arizona, where he learned how important water is in the American West. In this program, as in his book by the same title, he describes how dependent we are upon the Colorado River, as well as the wildlife refuges, recreation areas, and cities along its length. He describes its natural and human history, which would not be complete without the description of the dams, irrigation, and flood control projects along its length. With gorgeous photography, Turner follows the river’s flow from the headwaters to the Gulf of California, beginning with its main tributary, the Green River. More than 50 rivers and streams from seven states feed the mighty Colorado, while also providing water for tens of millions of people downstream. Join us for the story of the Colorado River. At the Performing Arts Center. Seating is on a first-come basis. Open to the public: $10 at the door; ABDNHA Members: no charge.

The Cary Ranch, usually closed to the public, is located atop Coyote Canyon in Anza.

Our tour of this California Historical Landmark will include visits to morteros, rock art, the Cary home, and Clark’s adobe home ruins. Wear sturdy shoes for slow walking totaling about 1 mile with vegetation and rocky terrain. Good balance needed to ascend moderately steep boulders for a short distance.

4WD Jacumba Mountain.
Ed Pollock - ABDNHA Volunteer
We will meet 9 AM at the Jacumba Hot Springs Spa and Resort, 44500 Old Hwy 80, Jacumba 91934, 619 766-4333 From there we will drive to the trip start, some 4 miles east of the Spa, leaving the pavement and beginning a steep uphill climb into the mountain area. All driving will be done on an old established mining road. It is narrow, in deep need of repair and an enjoyable, somewhat challenging 4wd trip. Due to road conditions, recommended vehicles are short wheel based, high clearance 4wd vehicles in proper working condition. Near the end of the road we have a nice location set for our potluck lunch. Please bring something to share.
As in the past, BBQ meat will be provided. Prior to the lunch, an optional walk is offered allowing a close up view of this boulder studded scenic area. Included is an experience at the international border with Mexico, passports not required. Jacumba resident and back country expert Bill Pape will be joining us to share his knowledge and history of the area, pointing out and possibly exploring several key natural features and historical locations. This trip is on BLM land and, as an organized group, we must limit participation to 15 people.
We cannot guarantee all those without 4wd vehicles will be able to share a ride. As a side note, the Jacumba Spa is a functioning resort type inn. With motel rooms available they also have a daily breakfast available to the public starting at 7 AM. They are very accommodating and know our guide Bill Pape very well. Jacumbaresort.com
