Red Box is the name of the junction of the Angeles Crest Highway, the Mt. Wilson-Red Box Road, and the Rincon - Red Box Road. It is located at the 1,422 meter (4,666') saddle between Mount Lawlor and San Gabriel Peak. The saddle separates the upper Arroyo Seco drainage from the West Fork of the San Gabriel River.
It was named for the red box which used to contain fire fighting tools and supplies. A campground and a cultural center for the Hahamongna tribe are located at the site. It is used as a drop off point to Camp Hi-Hill.
