Another shadow on the land: Arroyo de los Jardines, whose source is under the Hollywood Hills, runs the length of the Wilshire Country Club and then dives underground before appearing again south of Wilshire and east of Highland, running for about four blocks between the backs of 400 homes in the Brookside neighborhood before going underground again. The stream travels beneath La Brea until finally joining Ballona Creek.
