Vanishing Island
Vanishing island refers to any permanent island which is exposed at low tide but is submersed at high tide. Vanishing islands occur globally. There are vanishing islands in the Philippines and several in the San Juan Islands. In early times, seamen were confused by this phenomenon and invented explanations for it, usually involving a massive sea monster that would let a crew land on its back before submersing itself, drowning the crew. Notable examples of these include the aspidochelone, Fastitocalon, Jasconius, Lyngbakr, Hafgufa, and various accounts of the kraken. There is a vanishing island off the west coast of Samal Island in the Philippines. See also * Tidal island A tidal island is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide.

Mudflat
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Austral ...

Oxon Creek
Oxon Creek is a stream on the Potomac River which feeds a cove that straddles the border between Washington, D.C. and Prince George's County, Maryland just north of Interstate 495 (Capital Beltway) at Woodrow Wilson Bridge. Oxon Creek heads at the confluence of Oxon Run and Barnaby Run, sometimes referred to as Winkle Doodle Run. It starts just inside the boundary of D.C. and then runs to the south and west into Maryland to empty into the Potomac at Goose Island (a sand bar often under water) across from the city of Alexandria, Virginia. Before reaching the Potomac, the creek widens to form Oxon Cove which is partially in Maryland and partially in Washington, D.C.. The creek is almost entirely within Oxon Cove National Park, except for the first few feet in D.C. and a portion of the cove on the southside of the Blue Plains Advanced Wastewater Treatment Plant. Two bridges cross the creek. The Anacostia Freeway crosses it on a bridge where it becomes a tidal stream and the Oxon Hi ...

Woodrow Wilson Bridge
The Woodrow Wilson Memorial Bridge (also known as the Woodrow Wilson Bridge or the Wilson Bridge) is a bascule bridge that spans the Potomac River between the independent city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland, United States. The original bridge was one of only a handful of drawbridges in the U.S. Interstate Highway System. It contained the only portion of the Interstate system owned and operated by the federal government until construction was completed and it was turned over to the Virginia and Maryland departments of transportation. The Wilson Bridge carries Interstate 95 (I-95) and I-495 (the Capital Beltway). The drawbridge on the original span opened about 260 times a year, frequently disrupting traffic on a bridge that carried about 250,000 cars each day. The new, higher span requires fewer openings. The bridge's west abutment is in Virginia, a small portion is in Washington, D.C., and the remaining majority of it is with ...
