Devils Canyon, Canyon in the Jacumba Mountains, California, United States

Devils Canyon is a steep canyon in the Jacumba Mountains, straddling Imperial and San Diego Counties, California. Its mouth lies at 1,109 feet in Imperial County, and its head reaches 3,560 feet at 32°41′06″N 116°08′42″W in San Diego County. Loose tan and gray rock, scattered boulders and pale gravel cover the slope above a sandy dirt track that curves between low green shrubs and large gray rocks.
