Cajon Canyon
Cajon Canyon, originally named El Cajon De San Gabriel De Amuscopiabit, El Cajon in Spanish meaning "the box" in English, is a long valley ending in a box canyon in the northeastern San Gabriel Mountains, within San Bernardino County, California. == Geography == The steep slopes around the edges of the box canyon section in its upper reaches, making it difficult to enter and leave it, led to its acquiring this name Cajon.
