Crowder Canyon
Crowder Canyon, originally Coyote Canyon, is a valley in San Bernardino County, California. Its mouth was at an elevation of 2,999 feet / 914 meters at its confluence with Cajon Canyon. Its source was at an elevation of 4200 feet at 34°21′02″N 117°26′04″W / 34.35056°N 117.43444°W near Cajon Summit. The canyon runs southward just west of the top of Cajon Pass then turns southwestward to meet Cajon Canyon.
As Coyote Canyon, what is now Crowder Canyon, was the route that first the Old Spanish Trail and then the Mormon Road passed through the Cajon Pass. Antonio Armijo, who pioneered the Old Spanish Trail, did not cross over the San Bernardino Mountains by the Mojave Trail route over Monument Peak but followed a route he called "Cañon de San Bernardino" from the upper Mojave River west through Cajon Pass and down Crowder Canyon and then Cajon Canyon. It was known to the vaqueros of the San Bernardino de Sena Estancia who had come to the aid of Armijo's party with food. This route ran along the course of Crowder Canyon to its mouth at Cajon Canyon and down to the mouth of the canyon at Sycamore Grove.
