San Bruno Mountain is located in northern San Mateo County, California, with some slopes of the mountain crossing over into southern San Francisco. Most of the mountain lies within the San Bruno Mountain State Park, a unique open-space island in the midst of the San Francisco Peninsula's urbanization. Next to the state park is the state San Bruno Mountain Ecological Reserve on the north slope. It is near the southern boundary of San Francisco, surrounded by the cities of South San Francisco, Daly City, Colma, and Brisbane. San Bruno Mountain is topped by a four mile long ridge. Trails to the summit afford expansive views of the San Francisco Bay Area. Radio Peak (elevation )〔 is the highest point, hosting several radio broadcast towers, KTSF television, ION's KKPX television and NBC's KNTV Television, serving a huge area that would otherwise have poor service in the hilly Bay Area region. The mountain provides habitat for several species of rare and endangered plants and butterflies. The endangered San Bruno elfin butterfly inhabits this mountain and a few other locations. The distinct Franciscan fog zone plants of San Bruno Mountain set it apart from other California coastal areas.〔(California Department of Fish and Game's website, San Bruno Ecological Reserve. )〕 ==Recorded history== The Portola expedition visited San Francisco Bay in 1769. The expedition is usually considered the first European presence in the area. Five years later Fernando Rivera and four soldiers climbed the mountain and watched sunrise across the bay. The mountain was named by Bruno de Heceta for his patron saint. San Bruno Mountain consists of portions of five Mexican land grants; the southernmost being Rancho Buri Buri. Jose Antonio Sanchez, who rode by mule as a child from Sonora, Mexico was given Rancho Buri Buri in 1827, with confirmation in 1835. Rancho Buri Buri extended from the bay salt flats to San Andreas Valley and from Colma to Burlingame. Rancho Canada de Guadalupe la Visitacion y Rodeo Viejo contained most of the present day San Bruno Mountain; this rancho contains the city of Brisbane, Guadalupe Valley, Crocker Industrial Park, Visitacion Valley and the old rodeo grounds by Islais Creek. In 1835 this rancho was granted to Jacob P. Leese. In 1884 banker Charles Crocker acquired core holdings of this rancho amounting to from Leese's successors, and that land devolved to the Crocker Estate Company, who are the present day owners of San Bruno Mountain. Three other ranchos held minor portions of the northern flank of San Bruno Mountain. The cities that have grown up around the mountain are San Francisco to the north, Brisbane to the east, South San Francisco to the south and both Daly City and Colma to the west. Nossaman attorney Robert D. Thornton pioneered the Habitat Conservation Plan (HCP) concept creating the first such plan for the area around San Bruno Mountain. KRON (Channel 4) was the first television station to place a transmitter tower on Radio Peak, in 1949, followed by KQED and KTVU, though these tenants moved their transmitters to Sutro Tower in the 1970s. A number of FM stations built transmitter towers on the mountain, and in 2005, KNTV moved its transmitter to the mountain, on the former KCSM-TV tower. KTSF occupies the former KRON site. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「San Bruno Mountain」の詳細全文を読む スポンサード リンク
