West Coast of the United StatesThe West Coast of the United States, also known as the Pacific Coast and the Western Seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but it occasionally includes Alaska and Hawaii in bureaucratic usage. For example, the U.S. Census Bureau considers both states to be part of a larger U.S. geographic division.
Military prisonA military prison is a prison operated by a military. Military prisons are used variously to house prisoners of war, unlawful combatants, those whose freedom is deemed a national security risk by the military or national authorities, and members of the military found guilty of military offenses. There are two types: penal and confinement-oriented, where captured enemy combatants are confined for military reasons until hostilities cease.
Federal prisonA federal prison is operated under the jurisdiction of a federal government as opposed to a state or provincial body. Federal prisons are used for people who violated federal law (U.S., Mexico), people considered dangerous (Brazil), or those sentenced to longer terms of imprisonment (Canada). Not all federated countries have a legal concept of "federal prison". AustraliaThe Australian federal government directly controls only a few detention facilities.
Golden GateThe Golden Gate is a strait on the west coast of North America that connects San Francisco Bay and the Pacific Ocean. It is defined by the headlands of the San Francisco Peninsula and the Marin Peninsula, and, since 1937, has been spanned by the Golden Gate Bridge. The entire shoreline and adjacent waters throughout the strait are managed by the Golden Gate National Recreation Area.
Western gullThe western gull (Larus occidentalis) is a large white-headed gull that lives on the west coast of North America and the Pacific Ocean. The western gull ranges from British Columbia, Canada, to Baja California, Mexico. It was previously considered conspecific with the yellow-footed gull (Larus livens) of the Gulf of California.

LighthouseA lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation.StraitA strait is a water body connecting two seas or water basins. The surface water is, for the most part, at the same elevation on both sides and can flow through the strait in either direction, although the topography generally constricts the flow somewhat. In some straits, there is a dominant directional current. Most commonly, the strait is a narrow channel that lies between two land masses.
SeabirdSeabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, while modern seabird families emerged in the Paleogene.*As an Amazon Associate I earn from qualifying purchases.
