San Bruno Creek (Spanish for: "St. Brun") is an intermittent stream that rises on the eastern slopes of the Northern Santa Cruz Mountains in San Mateo County, California, USA.〔U.S. Geological Survey, ''Montara Mountain Quadrangle, 7.5 Minute Series'', U.S. Government Printing Office, Washington, D.C.〕 The headwaters descend a relatively steep canyon east of Skyline Boulevard in a tortuous course. Comparison of topographic maps from 1896 and 1939 illustrates the extreme modification in the lower reaches due to urban development from the rapidly expanding population.〔(Topographic Maps of the San Bruno Creek Watershed: 1896 and 1939 )〕 The San Bruno Creek watershed was originally settled by a tribe of the Ohlone, and later this locale was part of the Spanish missions' landholdings. A hiking trail winds along San Bruno Creek representing an important link in the San Francisco Bay Trail; in fact, this link is needed to make up for lack of access along a large bay front area occupied exclusively by San Francisco International Airport; thus, the Bay Trail must detour a full two miles inland from the bay to meet the San Bruno Creek Trail.〔(San Francisco Bay Trail in the vicinity of Point San Bruno )〕 ==History== Prehistorically the banks of San Bruno Creek were settled by the Buriburi tribe of the Ohlone, who are imputed to have lived there as early as 2000 BC. One Buriburi campsite has been identified along San Bruno Creek, which may have had a population of 15 to 25 people.〔(City of San Bruno, California Official Site )〕 This watershed was first explored by Europeans in 1769 by a Spanish expedition led by Gaspar de Portolà. Later, more extensive explorations by Bruno Hecate resulted in the naming of San Bruno Creek after St. Bruno of Cologne, the founder of a medieval monastic order. This creek later gave its name to the community. With the establishment of the San Francisco de Asís (St. Francis of Assisi) mission, much of the catchment basin became pasture for grazing mission livestock. Following the decline of the missions, the San Bruno Creek watershed became part of Rancho Buri Buri granted to José de la Cruz Sánchez, the eleventh ''Alcalde'' (mayor) of San Francisco. Dairy farms later became common in much of the area. One of the earliest maps showing San Bruno Creek appeared in 1893, prepared by Andrew Cowper Lawson, professor of geology at the University of California, Berkeley. At that time San Bruno Creek was drawn as sharing headwaters with another creek which drained away from the bay into what is now called Crystal Springs Reservoir.〔(History of the naming of San Andreas Fault and Lake )〕 Later development of the reservoir by the city of San Francisco and lower reach urbanization by the city of San Bruno modified greatly the upper and lower reaches of the watercourse. 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 Creek」の詳細全文を読む スポンサード リンク
