Pigeon Point Lighthouse
Pigeon Point Light Station or Pigeon Point Lighthouse is a lighthouse built in 1871 to guide ships on the Pacific coast of California. It is the tallest lighthouse (tied with Point Arena Light) on the West Coast of the United States. It is still an active Coast Guard aid to navigation. Pigeon Point Light Station is located on the coastal highway ( State Route 1), south of Pescadero, California, between Santa Cruz and San Francisco. The , white masonry tower, resembles the typical New England structure. The lighthouse and the land around have been preserved as Pigeon Point Light Station State Historic Park, a California state park. The lighthouse is also listed on the National Register of Historic Places, and designated as a California Historical Landmark. The lighthouse is currently undergoing major renovations funded by the California state legislature in 2021. Research published 2022 by the San Mateo County Office of Sustainability found that the lighthouse was vulnerable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...

List Of Lighthouses In The United States
This is a list of lighthouses in the United States. The United States has had approximately a thousand lights as well as light towers, range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Lighthouses that are in former U.S. territories are not listed here. Most of the lights in the United States have been built and maintained by the Coast Guard (since 1939) and its predecessors, the United States Lighthouse Service (1910–1939) and the United States Lighthouse Board (1852–1910). Before the Lighthouse Board was established, local collectors of customs were responsible for lighthouses under Stephen Pleasonton. As their importance to navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership and in some cases responsibility for running them to other parties, the chief of them being the National Park Service under the National Historic Lighthouse Preservation ...

List Of Lighthouses In California
There are several lighthouses in the U.S. state of California, including a few listed on the National Register of Historic Places.Lighthouse Friends (California) Notable Faux Lighthouse Notes :A. Ballast Point Light was moved in 1960 to the bell tower which had served as a fog signal building as the 1890 tower had been declared unsafe. The light shone from the top of the bell tower until 1961 when it was replaced by an offshore light. :B. The tower was abandoned in 1971 when the beacon was moved to a nearby modern pole. This light was discontinued in 2013 fifteen years after the old tower was moved to a new spot and restored. :C. Parts of the old structure now have separate owners, today an automated beacon is in active service. :D. Light moved to a pole. :E. Old Point Loma Light was built a few months after the lighthouse at Point Pinos making it the second oldest in the state still standing.

Hostel
A hostel is a form of low-cost, short-term shared sociable lodging where guests can rent a bed, usually a bunk bed in a dormitory, with shared use of a lounge and sometimes a kitchen. Rooms can be mixed or single-sex and have private or shared bathrooms. Private rooms may also be available, but the property must offer dormitories to be considered a hostel. Hostels are popular forms of lodging for backpackers. They are part of the sharing economy. Benefits of hostels include lower costs and opportunities to meet people from different places, find travel partners, and share travel ideas. Some hostels, such as Zostel in India or Hostelling International, cater to a niche market of travelers. For example, one hostel might feature in-house social gatherings such as movie nights or communal dinners, another might feature local tours, one might be known for its parties, and another might have a quieter place to relax in serenity, or be located on the beach. Newer hostels focus on a mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Hatteras Lighthouse
Cape Hatteras Light is a lighthouse located on Hatteras Island in the Outer Banks in the town of Buxton, North Carolina and is part of the Cape Hatteras National Seashore. The lighthouse’s semi-unique pattern makes it easy to recognize and famous. It is often ranked high on lists of most beautiful, and famous lighthouses in the US. The Outer Banks are a group of barrier islands on the North Carolina coast that separate the Atlantic Ocean from the coastal sounds and inlets. Atlantic currents in this area made for excellent travel for ships, except in the area of Diamond Shoals, just offshore at Cape Hatteras. Nearby, the warm Gulf Stream ocean current collides with the colder Labrador Current, creating ideal conditions for powerful ocean storms and sea swells. The large number of ships that ran aground because of these shifting sandbars gave this area the nickname "Graveyard of the Atlantic." It also led the U.S. Congress to authorize the construction of the Cape Hatteras Li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verandah
A veranda or verandah is a roofed, open-air gallery or porch, attached to the outside of a building. A veranda is often partly enclosed by a railing and frequently extends across the front and sides of the structure. Although the form ''verandah'' is correct and very common, some authorities prefer the version without an "h" (the ''Concise Oxford English Dictionary'' gives the "h" version as a variant and '' The Guardian Style Guide'' says "veranda not verandah"). Australia's ''Macquarie Dictionary'' prefers ''verandah''. Architecture styles notable for verandas Australia The veranda has featured quite prominently in Australian vernacular architecture and first became widespread in colonial buildings during the 1850s. The Victorian Filigree architecture style is used by residential (particularly terraced houses in Australia and New Zealand) and commercial buildings (particularly hotels) across Australia and features decorative screens of wrought iron, cast iron "lace" or ...

Aerobeacon
An aerobeacon is a light assembly used to create a fixed or flashing signal visible over long distances. It consists of a high intensity electric lamp mounted with a focusing device in a cylindrical housing, which usually is rotated on a vertical axis by an electric motor. The sweep of the narrow beam thus produced gives the flashing effect. Aerobeacons were originally developed for aviation use, mostly as aerodrome beacons, but they also saw extensive use in lighthouses. They were far less expensive to manufacture and maintain than classic glass Fresnel lenses, and much more durable; they could be mounted and exposed to the weather. Historic models include the DCB-24, which used a single parabolic reflector; the DCB-224, a double-beamed version of the DCB-24; and the DCB-36, which used a system of plastic Fresnel type lenses. Manufacturers included Carlisle & Finch in Cincinnati and the Crouse-Hinds Company in Syracuse, New York. Aerobeacons have replaced fragile glass Fresnel le ...

Foghorn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help marine ...
