The Wiggle
The Wiggle is a zig-zagging bicycle route from Market Street to Golden Gate Park in San Francisco, California, that minimizes hilly inclines for bicycle riders. Rising , The Wiggle inclines average 3% and never exceed 6%. The path generally follows the historical route of the long since paved-over Sans Souci Valley watercourse, winding through the Lower Haight neighborhood toward the Panhandle section of Golden Gate Park. The lower end of the route begins at either end of the Duboce Bikeway in the block of Duboce Avenue just west of Market Street. The elevation is approximately above sea level. It then moves in a zig-zag toward the northwest along Duboce Avenue, Steiner, Waller, Pierce, Haight, Scott, and Fell Streets to the Panhandle Bikeway, above sea level. After climbing 50 more feet, the peak of The Wiggle is reached near Stanyan Street at the peninsular drainage divide, i.e., the dividing point between surface water flowing to the San Francisco Bay on the east ...

Sunset District
The Sunset District is a neighborhood located in the southwest quadrant of San Francisco, California, United States. Location The Sunset District is the largest neighborhood within the city and county of San Francisco. Golden Gate Park forms the neighborhood's northern border, and the Pacific Ocean (or, more specifically, the long, flat strand of beach known as Ocean Beach) forms its western border. A section of the Sunset District towards its southeastern end is known as the Parkside neighborhood. Prior to the residential and commercial development of the Sunset District, much of the area was covered by sand dunes and was originally referred to by 19th century San Franciscans as the " Outside Lands." The Sunset District and the neighboring Richmond District (on the north side of Golden Gate Park) are often collectively known as The Avenues, because the majority of both neighborhoods are spanned by numbered north-south avenues. When the city was originally laid out, the avenue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yelamu
The Yelamu are a local tribe of Ohlone people from the San Francisco Bay Area in Northern California. The Yelamu speak a language called Ramaytush. The moderAssociation of Ramaytush Ohlone (ARO)are the descendants of the Ramaytush. Randall Milliken's study, "A Time of Little Choice: The Disintegration of Tribal Culture in the San Francisco Bay Area 1769-1810," estimates that 160 to 300 Yelamu were living in San Francisco when the Spanish established Mission San Francisco de Asís on June 30, 1776. Artifacts have been found across San Francisco from at least 50 different locations during modern construction activities within the city that were originally left by family groups that moved seasonally between villages around present day San Francisco. Additional villages existed to the south of San Francisco as well. History According to anthropologists the Yelamu people and their Ohlone neighbors arrived here between 4,000-6,000 years ago. They live on the northern tip of the San F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intermittent Stream
Intermittent, temporary or seasonal rivers or streams cease to flow every year or at least twice every five years.(Tzoraki et al., 2007) Such rivers drain large arid and semi-arid areas, covering approximately a third of the earth's surface. The extent of temporary rivers is increasing, as many formerly perennial rivers are becoming temporary because of increasing water demand, particularly for irrigation. Despite inconsistent water flow, intermittent rivers are considered land-forming agents in arid regions, as they are agents of significant deposition and erosion during flood events. The combination of dry crusted soils and the highly erosive energy of the rain cause sediment resuspension and transport to the coastal areas.(Tzoraki et al., 2009) They are among the aquatic habitats most altered by human activities. During the summer even under no flow conditions the point sources are still active such as the wastewater effluents, resulting in nutrients and organic pollutants ...

Santa Cruz Mountains
The Santa Cruz Mountains, part of the Pacific Coast Ranges, are a mountain range in central and Northern California, United States. They form a ridge down the San Francisco Peninsula, south of San Francisco. They separate the Pacific Ocean from the San Francisco Bay and the Santa Clara Valley, and continue south to the Central Coast, bordering Monterey Bay and ending at the Salinas Valley. The range passes through the counties of San Mateo, Santa Clara, Santa Cruz, San Benito and Monterey, with the Pajaro River forming the southern boundary. Geography The northernmost portion of the Santa Cruz Mountains, north of Half Moon Bay Road ( SR 92), is known as Montara Mountain; the middle portion is the Sierra Morena, which includes a summit called Sierra Morena, and extends south to a gap at Lexington Reservoir; south of the gap, the mountain range is known as the Sierra Azul. The highest point in the range is Loma Prieta Peak, west of Morgan Hill, with a height of , near the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Miguel Hills
The Twin Peaks are two prominent hills with an elevation of about located near the geographic center of San Francisco, California. Only Mount Davidson is higher within the city.San Francisco Recreation and Parks Department (2006)"Twin Peaks", section 6.8 o''Significant Natural Resources Areas Management Plan''. Retrieved April 21, 2007. Location and climate The North and South Twin Peaks, also known as "Eureka" and "Noe" respectively, are about apart. The peaks form a divide for the summer coastal fog pushed in from the Pacific Ocean. Their west-facing slopes often get fog and strong winds, while the east-facing slopes receive more sun and warmth. Elevation at each summit is just over . Thin, sandy soil is commonplace on Twin Peaks, making them susceptible to erosion. On some rare occasions, Twin Peaks has been able to get a dusting of snow especially on February 5, 1976, when it got several inches of snow. Most recently on February 26, 2011, and February 5, 2019, Twin Peaks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Franciscan Assemblage
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas fault that defines the western extent of the assemblage. The Franciscan Complex is dominated by greywacke sandstones, shales and conglomerates which have experienced low-grade metamorphism. Other important lithologies include chert, basalt, limestone, serpentinite, and high-pressure, low-temperature metabasites (blueschists and eclogites) and meta-limestones. Fossils like radiolaria are found in chert beds of the Franciscan Complex. These fossils have been used to provide age constraints on the different terranes that constitute the Franciscan. The mining opportunities within the Franciscan are restricted to deposits of cinnabar and limestone. The outcrops of the formation have a very large range ...

Buena Vista Park
Buena Vista Park is a park in the Haight-Ashbury and Buena Vista Heights neighborhoods of San Francisco, California San Francisco (; Spanish for " Saint Francis"), officially the City and County of San Francisco, is the commercial, financial, and cultural center of Northern California. The city proper is the fourth most populous in California and 17th .... It is the oldest official park in San Francisco, established in 1867 as Hill Park, later renamed Buena Vista. It is bounded by Haight Street to the north, and by Buena Vista Avenue West and Buena Vista Avenue East. The park is on a steep hill that peaks at , and covers . The lowest section is the north end along Haight. Layout The hill on which the park lies is composed primarily of sand and San Francisco chert, formed in the Mesozoic era. The layout of the park uses the steepness of the hill to good advantage, offering good views of the city (particularly to the north). At the peak of the park is a small lawn. N ...

Corona Heights
Corona Heights is a neighborhood in San Francisco, California, just north of Market Street and Eureka Valley. Corona Heights is often considered part of the Castro and Upper Market areas. Location The Corona Heights neighborhood stretches between Buena Vista Park and Eureka Valley. The streets within Corona Heights were literally cut out of the large hill that once encompassed all of Buena Vista Park and extended all the way down to Market Street. History In 1899, excavation began on the hill to make way for the Gray Brothers Quarry and brick factory. The quarry had removed tons of rock and produced tens of thousands of bricks, creating a blasted landscape. George and Harry Gray (the Gray brothers) owned a total of three quarries in San Francisco. Besides The Corona Heights Quarry, One was located on Telegraph Hill, and the third at Thirtieth and Castro (now called Billy Goat Hill) located above Noe Valley. They had a bad reputation that was well deserved. Of the bricks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lone Mountain (California)
Lone Mountain is a neighborhood and a historic hill in west-central San Francisco, California. It is the present-site of the private University of San Francisco (USF) Lone Mountain Campus. It was once the location of the Lone Mountain Cemetery, a complex encompassing the Laurel Hill, Calvary, Masonic, and Odd Fellows Cemeteries. History Lone Mountain is one of San Francisco's historic hills. The Spanish name for Lone Mountain was El Divisadero, from the Spanish ''divisadero'', which means a point from which one can look far.
