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.
