Ring Mountain is an elevated landform on the Tiburon Peninsula in Marin County, California. This mountain was named for George E. Ring, who served as a Marin County Supervisor from 1895 to 1903.[3]
A number of rare and endangered plant species inhabit Ring Mountain.[4] The mountain's twin summits consist of serpentinite,[5] a rock which is very high in magnesium, producing soils of unusual chemistry (serpentine soil). The landscape is strewn with many sizable boulders which exhibit a variety of lithologies including high-pressure metamorphic rocks of amphibolite, blueschist, greenschist, and eclogite grade.[6]
Native American pecked curvilinear nucleated petroglyphs created by the Coast Miwok people are also found here.[7]
