Context paragraphs:
William Penn Landing Site: The monument at the William Penn Landing Site marks the spot of the first landing of William Penn on the territory of Pennsylvania, on October 28 or 29, 1682 (O.S.).  Penn, the founder of the Province of Pennsylvania, landed in the only town in the province, then known as Upland, but since known as Chester.

Seventeen Seventy, Queensland: Seventeen Seventy, also written as 1770, is a town and locality in Gladstone Region, Queensland, Australia, built on the site of the second landing by James Cook and the crew of HM Bark Endeavour in May 1770 (Cook's first landing in what is now the state of Queensland).  Originally known as Round Hill – after the creek it sits on – the name was changed in 1970 to commemorate the bicentenary of Cook's visit.  The community of Seventeen Seventy hold the re-enactment of this historic landing each year as part of the 1770 Festival held in May.

Alwyn Ruddock: Alwyn Ruddock (1916–2005) was a noted British historian of the Age of Discovery, best known for her research on the "English" voyages of the 15th-century explorer John Cabot.  Cabot and other English navigators of the time were trying to find lands to the West, such as the mythical "Isle of Brasil" or the North American lands first discovered by Icelanders in previous centuries.

Acadian Landing Site: The Acadian Landing Site, also known as the Acadian Cross Historic Shrine, is a site historically significant to the French-American Acadian population of far northern Maine.  Located on the southern bank of the Saint John River east of Madawaska and marked by a large marble cross, it is the site traditionally recorded as the landing point of the first Acadians to settle this region of the upper Saint John River.  The site was listed on the National Register of Historic Places in 1973.

Hadley–Apennine: Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth manned landing on the Moon and the first of the "J-missions", in July 1971.  The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis.  Hadley-Apennine is bordered by the Montes Apenninus (often referred to as "Apennine Front"), a mountain range, and Hadley Rille, a meandering channel, on the east and west, respectively.

Tuscumbia Landing Site: The Tuscumbia Landing Site is a historic port site near Sheffield, Alabama.  The landing was established in 1824 at the mouth of Spring Creek on the Tennessee River.  As large craft could not navigate Spring Creek to reach Tuscumbia, the landing was built to transfer goods to and from the town.  The New Orleans and Tuscumbia Steamboat Company was created in 1825, and connected The Shoals with towns on the Mississippi and Ohio Rivers.  Wagons were used to haul goods between the landing and the town until a horse-drawn railroad, the first railroad west of the Appalachian Mountains, was built from 1831 to 1832.  The line was later extended to Decatur in 1834, bypassing the treacherous shoals on the Tennessee River, and was renamed the Tuscumbia, Courtland and Decatur Railroad.  The landing was also a stop for many Muscogee and Cherokee along the Trail of Tears.

Fountain of Youth Archaeological Park: The Fountain of Youth Archaeological Park is a privately owned 15 acre park in St. Augustine, Florida, located along Hospital Creek, part of the Intracoastal Waterway.  It has been touted as the likely 1513 Florida landing site of Spanish explorer Ponce de Leon, although no evidence has been found to substantiate this claim.  Recent research by amateur historian Douglas Peck has placed another possible landing site in the vicinity of Melbourne Beach in Brevard County.  The park contains an artesian well claimed to be the freshwater source referred to by Antonio de Herrera y Tordesillas in his "Historia general de los hechos de los castellanos en las Islas y Tierra Firme del mar Océano" and supposedly sought by Ponce de Leon, but there is no supporting evidence.  Archaeological excavations made by Dr. Kathleen Deagan on the park's grounds in the 1990s uncovered remains of the first Spanish settlement and its fortifications in St. Augustine.

John Cabot: John Cabot (Italian: "Giovanni Caboto" , Venetian: "Zuan Chabotto" ; c. 1450 – c. 1500) was a Venetian navigator and explorer whose 1497 discovery of the coast of North America under the commission of Henry VII of England was the first European exploration of the mainland of North America since the Norse visits to Vinland in the eleventh century.  To mark the celebration of the 500th anniversary of Cabot's expedition, both the Canadian and British governments elected Cape Bonavista, Newfoundland, as Cabot's first landing site.  However, alternative locations have also been proposed.

Eberswalde (crater): Eberswalde, formerly known as Holden NE, is a partially buried impact crater in Margaritifer Terra, Mars.  Eberswalde Crater lies just to the north of Holden Crater, a large crater that may have been a lake.  The 65.3-km-diameter crater, centered at 24°S, 33°W, is named after the German town of the same name, in accordance with the International Astronomical Union's rules for planetary nomenclature.  It was one of the final four proposed landing sites for the Mars rover Mars Science Laboratory mission.  This extraterrestrial geological feature lies situated within the Margaritifer Sinus quadrangle (MC-19) region of Mars.  Although not chosen, it was considered a potential landing site for the "Mars 2020" rover, and in the second Mars 2020 Landing Site Workshop it survived the cut and was among the top eight sites still in the running.

Maryland Day: Maryland Day is a legal holiday in the U.S. state of Maryland.  It is observed on the anniversary of the March 25, 1634, landing of the first European settlers in the Province of Maryland, the third English colony to be settled in British North America.  On this day settlers from ""The Ark"" and the smaller ""The Dove"" first stepped foot onto Maryland soil, at St. Clement's Island in the Potomac River.  The settlers were about 150 in number, departed from Gravesend on the Thames River downstream from London.  Three Jesuit priests were collected from Cowes on the Isle of Wight in England where they avoided having to give the oath of allegiance and supremacy to the King.  The colony's grant was renewed to Cecil Calvert, 2nd Baron Baltimore, (1605-1675), two years prior by Charles I of England, after first being given to his father Sir George Calvert, 1st Baron Baltimore, (1574-1632), along with the title of "Lord Baltimore", and a first grant in Acadia, in Newfoundland, (modern Canada), (title named after lands and town Baltimore, in Ireland) who had served the King in many official and personal capacities as Secretary of State, 1619-1625 (despite his conversion to Roman Catholicism).  In thanksgiving for the safe landing, Jesuit Father Andrew White celebrated the Mass for the colonists led by the younger brother of Lord Baltimore, Leonard Calvert, (1606-1647), who served as the first governor, and perhaps for the first time ever in this part of the world on the first landing at Blackistone Island, later known as St. Clement's Island off the northern shore of the Potomac River, which was the new border between the new colony and the earlier English settlements in Virginia) and erected a large cross.  The landing coincided with the Feast of the Annunciation, a holy day honoring Mary, and the start of the new year in England's legal calendar (prior to 1752).  Maryland Day on 25 March celebrates the 1634 landing at St Clements.  Later the colonists and their two ships sailed further back down river to the southeast to settle a capital at St. Mary's City near the point where the Potomac flows into the Chesapeake Bay.
