Goat Canyon (Spanish: Cañón de los Laureles) also known as Cañón de los Laureles, begins in Tijuana, Mexico, and ends in the United States just north of the Mexico–U.S. border. The canyon is formed by Goat Canyon Creek, which receives water and other runoff from areas south of the border. Most of the canyon and its watershed lies within Baja California. The canyon originated during the Quaternary period; it is bordered by Bunker Hill to its west and Spooner's Mesa to its east. Part of the canyon contains coastal salt marshland and supports numerous sensitive and endangered species.
