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:Field Trip: Geology of San Diego County’s Peninsular Ranges - FULL (waitlist)
DESCRIPTION:Special Earth Science Series! \nFIELD TRIP IS FULL – PLEASE CALL ABDNHA at 760-767-3098 to get on waitlist \nLeader: Geologist Don Barrie \nNote the  start and end locations detailed below. Don will lead the group on an exploration of the rocks along Sunrise Hwy.\, west of Borrego Springs. The rocks in this area comprise part of a regional geologic suite known as the Peninsular Ranges Batholith (PRB)\, which extends from southern Baja\, California\, northward into the Palm Springs area. We’ll meet near the intersection of Sunrise Hwy. and Interstate 8\, then follow Sunrise Hwy. into the Laguna Mountains\, stopping to examine rock exposures along the way. The last stop will be in Julian\, where the group will tour the Eagle/High Peak gold mine and learn about the gold rush in Julian during the 1870s. On the field trip\, we’ll discuss the geologic story of how the gold got into the rocks. During the gold mine tour\, we’ll learn how hard-rock miners got the gold out of the rocks. To register\, go to www.abdnha.org\, or call the Nature Center at 760-767-3098. General Public: $20\, Members: $14\, Volunteers: $10. Please note that an additional $14 entrance fee per person is required\, payable upon entry to the mine. \nStart and end locations details: 9:00 am – 3:00 pm\, Sun.\, Jan. 25\, ending at the Eagle-High Peak mine in Julian. Meet at 9:00 am along Sunrise Hwy. (County Rd. S1)\, about 1/4-mile north of the Interstate 8 Sunrise Hwy. exit\, in a dirt parking area along the east side of the road.

SUMMARY:Field Trip: Borrego’s Strontium Volcano (Moderate) - FULL (waitlist)
DESCRIPTION:FIELD TRIP IS FULL. Call 760-767-3098 to get on waitlist. \nLeader: John Peterson\, Hydrologist and Geologist\nVisit this interesting old mine site\, active in the 1940s\, located north of the entrance to Fish Creek and north of the gypsum mine. The deposit was mined for strontium in WWII\, which was used in flares during the war. The deposit likely formed during an extrusive hydrothermal event when the mineral was extruded through surface vents. These vents are still present on the surface of the deposit. This moderate hike is about a 1.5-mile roundtrip with a vertical gain of 500 feet on an old mining road and trail. The surface is rough and rocky\, so hiking shoes are required\, and hiking poles recommended. We will start and return in the ABDNHA parking lot and carpool as needed. From ABDNHA\, the drive to the site includes 0.5 miles on Fish Creek Road\, which is rocky with areas of soft sand. High clearance is required\, and 4WD recommended. No charge\, but registration is required\, 760-767-3098.

SUMMARY:Field Trip: Ancient Lake Cahuilla
DESCRIPTION:FIELD TRIP IS FULL. Call 760-767-3098 to get on waitlist. \nLeader: John Peterson\, Hydrologist and Geologist\nStarting approximately 12\,000 years ago\, the Colorado River periodically changed its course\, flowing north into the Salton Sink and creating a massive prehistoric lake. For thousands of years\, this lake filled and dried up repeatedly\, becoming an important source of food and water for the Cahuilla\, Kumeyaay\, and Cocopah peoples. The last time the lake was filled was between 1731 and 1733. Hydrologist John Peterson will lead this half-day field trip to the Salton Sea\, providing an opportunity to look back in time and explore the remnants of the ancient lake\, including the ancient shoreline (the “bathtub ring”) that is still visible and the fish traps along the old shoreline. 15 people. General Public: $18\, Members: $12\, Volunteers: $10. Register online or at the Nature Center\, 760-767-3098.
