Belvedere Island
Belvedere Island (formerly, El Potrero de la Punta del Tiburon, Kashow's Island, Peninsula Island, Promontory Island, and Still Island) is a rocky island in the San Francisco Bay in Marin County, California which was formerly separated by a marsh from the mainland, though has since been linked by two spits. Part of the town of Belvedere, California is located on the island. Natural history There are a variety of flora and fauna represented on Belvedere Island. Presence of herons has been noted for a considerable period of time. Some of the flora are common to nearby Ring Mountain (on the Tiburon Peninsula), where a considerable floral biodiversity has been documented. Ring Mountain has also been established to have been a settlement area for early Native American inhabitants of this local area.C. Michael Hogan (2008''Ring Mountain'' The Megalithic Portal, ed. A.

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and ''Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Ring Mountain, California
Ring Mountain is an elevated landform on the Tiburon Peninsula in Marin County, California. This mountain was named for George E. Ring, who served as a Marin County Supervisor from 1895 to 1903. A number of rare and endangered flora inhabit Ring Mountain. The mountain's twin summits consist of serpentinite, a rock which is very high in magnesium, producing soils of unusual chemistry (serpentine soil). The landscape is strewn with many sizable boulders which exhibit a variety of lithologies including high-pressure metamorphic rocks of amphibolite, blueschist, greenschist, and eclogite grade. Native American pecked curvilinear nucleated petroglyphs created by the Coast Miwok people are also found here. Geology Ring Mountain is a unique geological site, where rocks that formed in ancient subduction zones can be observed. Serpentinized peridotite crops out on the two summits of the mountain, and the steep upper slopes are underlain by serpentinite-matrix mélange. The melange c ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Miwok
Coast Miwok are an indigenous people that was the second-largest group of Miwok people. Coast Miwok inhabited the general area of modern Marin County and southern Sonoma County in Northern California, from the Golden Gate north to Duncans Point and eastward to Sonoma Creek. Coast Miwok included the Bodega Bay Miwok, or Olamentko (Olamentke), from authenticated Miwok villages around Bodega Bay, the Marin Miwok, or Hookooeko (Huukuiko), and Southern Sonoma Miwok, or Lekahtewutko (Lekatuit). Culture The Coast Miwok spoke their own Coast Miwok language in the Utian linguistic group. They lived by hunting and gathering, and lived in small bands without centralized political authority. In the springtime they would head to the coasts to hunt salmon and other seafood, including seaweed. Otherwise their staple foods were primarily acorns—particularly from black and tan oak–nuts and wild game, such as deer and cottontail rabbits and black-tailed deer, ''Odocoileus hemionus columbian ...

California Gold Rush
The California Gold Rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood, in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation and the California genocide. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii) and Latin America in late 1848. Of th ...

Belvedere Lagoon
__NOTOC__ Belvedere Lagoon is an artificial lagoon on San Francisco Bay in Belvedere in Marin County, California. Narrow strips of land separate it from Richardson Bay (to the northwest) and Raccoon Strait. The lagoon is owned and maintained by the Belvedere Lagoon Property Owners' Association. The lagoon is not accessible by boat from San Francisco Bay, and no public access is provided. Until somewhat late in the 20th century houseboats were present in Belvedere Lagoon.Russell Conder. 1992 There used to be a natural passage between the lagoon and the San Francisco Bay through the southern spit. The passage was spanned by a drawbridge. From the late 19th century, the drawbridge would be raised twice a year, once in the Spring to allow pleasure boats of the Corinthian Yacht Club to exit the lagoon, where the boats wintered, and go to their Summer moorings, and once in the Fall, to allow the boats to return. This raising of the drawbridge signaled the beginning of the pleasure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
