Seal Rocks (San Francisco, California)
Seal Rock (or ''Seal Rocks'') is a group of small rock formation islands in the Lands End area of the Outer Richmond District in western San Francisco, California. They are located just offshore in the Pacific Ocean, at the north end of the Ocean Beach, near the Cliff House and Sutro Baths ruins. The name is derived from the population of Steller's sea lions (''Eumetopias jubatus'') and California sea lions (''Zalophus californianus''), who haul out on the rock. Both species are often colloquially called "seals". The formations and wildlife are protected within the Golden Gate National Recreation Area. Geology Near the end of the last ice age, this part of the coastline was thought to be between eight and twenty five miles westward of its current position - around five thousand years ago, with the melting of the ice, the sea level rose to its current level. The coastal features found here today were formed by the actions of waves, wind, and the movement of sand. The geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern California
Northern California (colloquially known as NorCal) is a geographic and cultural region that generally comprises the northern portion of the U.S. state of California. Spanning the state's northernmost 48 counties, its main population centers include the San Francisco Bay Area (anchored by the cities of San Jose, San Francisco, and Oakland), the Greater Sacramento area (anchored by the state capital Sacramento), the Redding, California, area south of the Cascade Range, and the Metropolitan Fresno area (anchored by the city of Fresno). Northern California also contains redwood forests, along with most of the Sierra Nevada, including Yosemite Valley and part of Lake Tahoe, Mount Shasta (the second-highest peak in the Cascade Range after Mount Rainier in Washington), and most of the Central Valley, one of the world's most productive agricultural regions. The 48-county definition is not used for the Northern California Megaregion, one of the 11 megaregions of the United States. Th ...

California Sea Lion
The California sea lion (''Zalophus californianus'') is a coastal eared seal native to western North America. It is one of six species of sea lions. Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. California sea lions are sexually dimorphic; males are larger than females, and have a thicker neck, and a protruding sagittal crest. They mainly haul-out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves. California sea lions feed on a number of species of fish and squid, and are preyed on by orcas and great white sharks. California sea lions have a polygynous breeding pattern. From May to August, males establish territories and try to attract females with which to mate. Females are free to move in between territories, and are not coerced by males. Mothers nurse their pups in between foraging trips. California sea lions communicate with numerous vocalizations, notably with bar ...

Sutro Heights Park
Sutro Heights Park is an historic public park in the Outer Richmond District of western San Francisco, California. It is within the Golden Gate National Recreation Area and the Sutro Historic District. It is located above the Cliff House in the Lands End area, with views of the Seal Rocks, Ocean Beach, and the Pacific Ocean. History The park is on the site of the former "Sutro Heights" estate of Adolph Sutro, a Comstock Lode silver baron, and a major land owner/developer in and mayor of San Francisco. In 1881, Adolf Sutro purchased of undeveloped land south of Point Lobos (San Francisco) and north of Ocean Beach at the western edge of the city. It included a promontory overlooking the Pacific, with scenic views of the Marin Headlands, Mount Tamalpais, and the Golden Gate. Sutro built his mansion on a rocky ledge there, above the first Cliff House. The grounds consisted of a spacious turreted mansion, a carriage house, and outbuildings set in expansive gardens. Th ...

49-Mile Scenic Drive
The 49-Mile Scenic Drive is a designated scenic road tour highlighting much of San Francisco, California. It was created in 1938 by the San Francisco Down Town Association to showcase the city's major attractions and natural beauty during the 1939 Golden Gate International Exposition. Originally beginning at San Francisco City Hall and ending on Treasure Island, the route has been modified several times since. Today the route forms a loop proceeding counterclockwise from Civic Center Plaza, and its length is closer to . Owing variously to its length, its labyrinthine route, and the difficulty of driving through a bustling city, the drive remains relatively unpopular with tourists and locals alike. In 2019, the ''San Francisco Chronicle'' proposed a non-driving alternative that it called the 49-Mile Scenic Route. Route description The drive begins on Polk St. opposite San Francisco City Hall.

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Merced Formation
The Merced Formation is a geologic formation in California, and also in Oregon and Washington state. It is named for Lake Merced, a natural lake on the western San Francisco coastline. Geology California In the coastal San Francisco Bay Area of California the Merced Formation was deposited in a small sedimentary basin that formed along the San Andreas Fault during the last two million years during the Pliocene age of the Neogene period, in the Cenozoic EraUSGS.gov: "San Andreas Fault and Coastal Geology, from Half Moon Bay to Fort Funston: Crustal Motion, Climate Change, and Human Activity" The fault cut the basin into two pieces and moved the pieces apart. It is found on the east side of the fault in western San Francisco and northern San Mateo County. On the west side of the fault it was carried north to the Bolinas headlands of western Marin County. Fort Funston is on a bluff made up of exposed sedimentary rocks of the Merced Formation, in San Francisco within the NPS Golden ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Twin Peaks, San Francisco, California
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] |
