Lime Kiln Point State Park
Lime Kiln Point State Park is a 42-acre Washington state park on the western shore of San Juan Island in the San Juan archipelago. The park is considered one of the best places in the world to view wild orcas from a land-based facility. Due to the unique bathymetric properties of the site, visitors on the shore can be within 20 feet of whales jumping out of the water ( breaching and spyhopping). It houses one of Friday Harbor's two lighthouses along with a stone lookout with picnic tables. The park was the site of lime kiln A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, Ca ...s beginning in 1860, and one kiln has been restored as a public exhibit. Activities and amenities The park provides opportunities for picnicking, hiking, beachcombing, orca watching, and tours of the still operat ...

Lime Kiln Lighthouse
The Lime Kiln Light is a functioning navigational aid located on Lime Kiln Point overlooking Dead Man's Bay on the western side of San Juan Island, San Juan County, Washington, in the United States. It guides ships through the Haro Straits and is part of Lime Kiln Point State Park, which offers tours during summer months. History The Lime Kiln Light was established in 1914 when acetylene lights were placed on Lime Kiln Point, a name derived from the lime kilns built there in the 1860s. It was the last major light established in Washington. The light was updated five years later with a octagonal concrete tower rising from the fog signal building, a design that matches the Alki Point Light in Seattle Seattle ( ) is a seaport city on the West Coast of the United States.

Whales
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Mysticetes include four extant (living) families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), and Eschrichtiidae (the grey whale). Odontocetes include the Monodontidae (belugas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, CaCO3 + heat → Calcium oxide, CaO + Carbon dioxide, CO2 This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere (unit), atmosphere), but a temperature around 1000 °C (1832 °F) (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. Early li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friday Harbor, Washington
Friday Harbor is a town in San Juan County, Washington, United States. The population was 2,162 at 2010 census. Located on San Juan Island, Friday Harbor is the major commercial center of the San Juan Islands archipelago and is the county seat of San Juan County. History In 1845 the Hudson's Bay Company laid claim to San Juan Island. In 1850 they built a salmon curing station. A few years later they started a sheep farm. The town's name originates from Joseph Poalie Friday, a native Hawaiian. Friday worked at the Pugets Sound Agricultural Company's Fort Cowlitz, from 1841 to 1859–60 and later moved north to San Juan Island, raising and herding sheep around the harbor. After the peaceful settlement obtained following the Pig War, the San Juan Islands became a separate county in 1873. Friday Harbor was named the county seat. Friday Harbor was officially incorporated on February 10, 1909. It remains the only incorporated town in the San Juan Islands. File:Salmon cannery ...

Spyhopping
Cetacean surfacing behaviour is a grouping of movement types that cetaceans make at the water's surface in addition to breathing. Cetaceans have developed and use surface behaviours for many functions such as display, feeding and communication. All regularly observed members of the order Cetacea, including whales, dolphins and porpoises, show a range of surfacing behaviours. Cetacea is usually split into two suborders, Odontoceti and Mysticeti, based on the presence of teeth or baleen plates in adults respectively. However, when considering behaviour, Cetacea can be split into whales (cetaceans more than 10 m long such as sperm and most baleen whales) and dolphins and porpoises (all Odontocetes less than 10 m long including orca tp://ftp.fao.org/docrep/fao/009/t0725e/t0725e10.pdf FAO Marine Mammals of the World, Suborder Odontoceti.) as many behaviours are correlated with size.

Bathymetric
Bathymetry (; ) is the study of underwater depth of ocean floors (''seabed topography''), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths ('' soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater depths. Seabed topography ...

San Juan County, Washington
San Juan County is a county located in the Salish Sea in the far northwestern corner of the U.S. state of Washington. As of the 2020 census, its population was 17,788. The county seat and only incorporated city is Friday Harbor, located on San Juan Island. The county was formed on October 31, 1873, from Whatcom County and is named for the San Juan Islands, which are in turn named for Juan Vicente de Güemes, 2nd Count of Revillagigedo, the Viceroy of New Spain. Although the islands themselves have no state highways, the ferry routes serving the islands are designated as part of the state highway system. History The San Juan Islands were the subject of a territorial dispute between Great Britain and the United States from 1846 to 1872, leading to the Pig War in 1859. The bloodless conflict ended through arbitration led by Kaiser Wilhelm I, which awarded the islands to the United States. San Juan County was home to Henry Cayou, one of the first elected officials of Native ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orcas
The orca or killer whale (''Orcinus orca'') is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus ''Orcinus'' and is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas. Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales. Orcas are apex predators, as they have no natural predators. They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
