Edgehill Mountain

Edgehill Mountain is a compact, seven-hundred-thirty-four-foot rise that served as the site of the Claremont Quarries in the early twentieth century. Investigators once linked explosives stolen from these specific quarries to the July nineteen-sixteen bombing during the city's Preparedness Day Parade. This tragedy, which killed ten people and injured forty, remains one of the most significant criminal investigations in San Francisco history. The land itself has seen a dramatic transition from an industrial rock source into a residential area, forever altering the landscape of this quiet corner of the city.
