Summary
[edit]DescriptionSan Bernardino Mountains, California (14331278337).jpg |
The San Bernardino Mountains are a high and rugged mountain range in Southern California in the United States. Situated north and northeast of San Bernardino and spanning two California counties, the range tops out at 11,489 feet (3,502 m) at San Gorgonio Mountain – the tallest peak in all of Southern California. The San Bernardinos form a significant region of wilderness and are popular for hiking and skiing. The mountains were formed about eleven million years ago by tectonic activity along the San Andreas Fault, and are still actively rising. Many local rivers originate in the range, which receives significantly more precipitation than the surrounding desert. The range's unique and varying environment allows it to maintain some of the greatest biodiversity in the state. For over 10,000 years, the San Bernardinos and their surrounds have been inhabited by indigenous peoples, who used the mountains as a summer hunting ground. Spanish explorers first encountered the San Bernardinos in the late 1700s, naming the eponymous San Bernardino Valley at its base. European settlement of the region progressed slowly until 1860, when the mountains became the focus of the largest gold rush ever to occur in Southern California. Waves of settlers brought in by the gold rush populated the lowlands around the San Bernardinos, and began to tap the mountains' rich timber and water resources on a large scale by the late 19th century. Recreational development of the range began in the early 1900s, when mountain resorts were built around new irrigation reservoirs. Since then, the mountains have been extensively engineered for transportation and water supply purposes. Four major state highways and the California Aqueduct traverse the mountains today; these developments have all had significant impacts on area wildlife and plant communities. The San Bernardinos run for approximately 60 miles (97 km) from Cajon Pass in the northwest – which separates them from the San Gabriel Mountains – to San Gorgonio Pass, across which lie the San Jacinto Mountains, in the southeast. The Morongo Valley in the southeast divides the range from the Little San Bernardino Mountains. Encompassing roughly 2,100 square miles (5,400 km2), the mountains lie mostly in San Bernardino County, with a small southern portion reaching into Riverside County. The range divides three major physiographic regions: the highly urbanized Inland Empire to the southwest, the Coachella Valley in the southeast, and the Mojave Desert to the north. Most of the range lies within the boundaries of the San Bernardino National Forest. Many cities lie at the base of the San Bernardino Mountains. These include San Bernardino, Redlands and Yucaipa in the south; Yucca Valley to the east; and Hesperia to the northwest. In addition, there are several mid-sized to large towns in the mountains themselves, including Big Bear City, Crestline, Lake Arrowhead and Running Springs. Cities within the San Bernardino Mountains total a population of about 44,000, with this number sometimes increasing tenfold during peak tourist season. en.wikipedia.org/wiki/San_Bernardino_Mountains en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
