Chavez Ravine is a shallow L-shaped canyon located in Los Angeles, California, United States, partially in the Elysian Park neighborhood. It sits in a large promontory of hills north of downtown Los Angeles and was known in the 1860s as the "Stone Quarry Hills" which had other smaller ravines such as Sulphur Ravine, Cemetery Ravine, Solano Canyon and Reservoir Ravine. It is next to Dodger Stadium, a baseball venue that opened in 1962. The name Chavez Ravine can be used to mean either the actual ravine itself in a narrow sense or sometimes in a broader sense the entire promontory and surrounding ravines, and is also used to refer to the stadium. Dodger Stadium was constructed by knocking down the ridge which separated the nearby Sulfur and Cemetery Ravines and filling those two ravines in. Palo Verde Elementary School was buried in the process. Chavez Ravine was named for Julian Chavez, a Los Angeles councilman in the 19th century. Chavez originally purchased the land in the Elysian Park area, which eventually grew to about 315 acres, in 1844. Nearby "Cemetery Ravine" was named after old Calvary, the first cemetery of Los Angeles.
