Just west of interstate highway 15 in the Cajon Pass about 19 miles north of San Bernardino at Junction 138, there are some interesting rock formations. Locally known as the Mormon Rocks, they are officially named part of the Rock Candy Mountains. The strange rock formations are proof of the San Andreas fault as these uplifts are at various angles from the horizon. The formations are dotted with holes and embedded stones everywhere poked out by the wind and weather through centuries. The formations are spread out for some distance along highway 138. Pockmarked and weather-worn though they appear, the Mormon Rocks are a series of cemented sandstone beds much more resistant to erosion than the surrounding gravel and silt sands. The Mormon Rocks stand out in relief called hogbacks above the alluvial flats of the Cajon Canyon wash. The rocks received their name from Mormon settlers, moving to the Los Angeles Basin from Salt Lake City in the mid 1800s.The Cajon Pass is a major automobile and rail transport corridor. The ATSF railway as well as highway 138 cuts right through this rock formation as shown in some of the displayed images. Recent updates to this gallery were from February 2011 just following a low elevation snow dusting of the area. These images really lend themselves to a strong infrared black and white treatment.
