This mark was inspired by the survey mark found near the lookout tower at the summit of Mount Tamalpais, located in the heart of Marin County, north of San Francisco's Golden Gate. Mount Tamalpais is not volcanic. It was formed by the tremendous grinding tectonic pressures where the Geologic North American and Pan Pacific plates meet. Tamalpais is unique in that it runs East and West. The name "tamalpais" is thought by some to be a combination of two Coast Miwok Indian words: "tamal" (bay, or coast) and "pais" (mountain).
