Although the archipelago may have been visited before by the Portuguese (who conquered Malacca City in 1511 and reached Maluku Islands in 1512 ), the earliest documented European expedition to the Philippines was that led by Ferdinand Magellan, in the service of the king of Spain.
 The expedition first sighted the mountains of Samar at dawn on the 16th March 1521, making landfall the following day at the small, uninhabited island of Homonhon at the mouth of the Leyte Gulf.
 On Easter Sunday, 31 March 1521, at Limasawa Island, Southern Leyte, as is stated in Pigafetta's Primo Viaggio Intorno El Mondo (First Voyage Around the World), Magellan solemnly planted a cross on the summit of a hill overlooking the sea and claimed for the king of Spain possession of the islands he had seen, naming them "Archipelago of Saint Lazarus".
Spring-heeled Jack is an entity in English folklore of the Victorian era.
 The first claimed sighting of Spring-heeled Jack was in 1837.
 Later sightings were reported all over Great Britain and were especially prevalent in suburban London, the Midlands and Scotland.
An 'albino' redwood is a redwood tree which is unable to produce chlorophyll, and so has white needles instead of the normal green.
 It survives by obtaining sugar through the connections between its roots and those of neighboring normal redwood(s), usually the parent tree from whose base it has sprouted.
 (Sap exchange through roots is a general phenomenon among redwoods.)
 About 400 are known.
 They can be found in both Henry Cowell Redwoods State Park and Humboldt Redwoods State Park, with eleven trees in the first.
 However, the exact locations are not publicized to protect the rare trees.
 They reach a maximum height of about 20 m (66 ft).
 Other conifers lack the ability to graft their roots, so 'albino' mutants of other species do not survive to become sizable trees.
 Albino Redwood sightings between Henry Cowell Redwoods State Park and Roaring Camp Railroads were first sighted by Roaring Camp CEO Georgiana P Clark in 2004 and reported and shared with naturalists at Henry Cowell Redwoods State Park and botanists at the University of California at Santa Cruz.
La Pinta (Spanish for "The Painted One" , "The Look", or "The Spotted One" ) was the fastest of the three ships used by Christopher Columbus in his first transatlantic voyage in 1492.
 The New World was first sighted by Rodrigo de Triana aboard "La Pinta" on 12 October 1492.
 The owner of "La Pinta" was Cristobal Quintero.
 The Quintero brothers were ship owners from Palos.
 The owner of the ship allowed Martin Alonso Pinzon to take over the ship so he could keep an eye on the ship.
The Springheel Saga is an audio drama series about the Victorian bogeyman, Spring-heeled Jack, written by Jack Bowman and Robert Valentine, and produced by The Wireless Theatre Company.
 The first series, "The Strange Case Of Springheel'd Jack", released in 2011 and starring Julian Glover, is based on the original 1837–38 Spring-heeled Jack sightings.
 Nicholas Parsons features in the second series, "The Legend Of Springheel'd Jack", which was released in 2013 and focuses on Spring-heeled Jack's absorption into popular culture in the 1840s.
 The third and final series, "The Secret Of Springheel'd Jack", released over 2015 and 2016, features Jenny Runacre and Matthew Kelly, and deals with the 1877 Aldershot barracks incident.
 The production was Wireless Theatre's first audio series, and is distributed as a digital download in MP3 format.
Succession Cliffs ( ) is a line of steep cliffs 1.5 nautical miles (2.8 km) extending along the east coast of Alexander Island, Antarctica, facing east towards George VI Sound immediately south of the mouth of Pluto Glacier.
 The cliffs were probably first sighted by Lincoln Ellsworth who photographed segments of the coast in this vicinity on November 23, 1935.
 First roughly surveyed from the ground in 1936 by the British Graham Land Expedition and resurveyed in 1948 by the Falkland Islands Dependencies Survey.
 So named by the FIDS because a geologic succession, or depositional sequence, is revealed by the accessible rock exposures of the cliffs.
The prehistory of Papua New Guinea can be traced back to about 60,000 years ago when people first migrated towards the Australian continent.
 The written history began when European navigators first sighted New Guinea in the early part of the 16th century.
Zebra Ridge ( ) is a prominent rock ridge, extending to about 2 miles (3.2 km) in length, situated 3 miles (4.8 km) south of the mouth of Tumble Glacier where it rises 760 m above the Roberts Ice Piedmont of east Alexander Island, Antarctica.
 The ridge was first sighted from a distance by Lincoln Ellsworth, who photographed the nearby Douglas Range from the air on November 23, 1935.
 First surveyed in 1948 by the Falkland Islands Dependencies Survey and so named because of the striped appearance of the rock strata.
Bungaroo is a locality near St. Ives, Sydney, Australia.
 The location is thought to be the site where Governor Arthur Phillip and party camped on the night of 16 April 1788 on the first of many expeditions intended to find arable land that could supply the Colony with agricultural products.
 The colony at Sydney Cove was dependent on supplies from England, but the soils around the harbour were too poor to support crops and sustain the Colony.
 This trip is very historic for the Ku-ring-gai Shire, being when Europeans first entered there.
 It is very historic for the entire Colony or State, being when the Blue Mountains were first sighted.
 It is believed from later statements made by Governor Phillip that he realized on seeing such large mountains that they must have a large river with rich alluvial soils.
 Thus the day after camping at Bungaroo the Colony's ultimate survival was realized, and it would be very soon indeed that the Governor would direct endeavour westwards with major consequences.
 As all that unfolded, unto this day, some consider that Bungaroo is the sole place recognizable in the colonists' writings of 1788 which now remains unchanged from as it was then.
Jabet Peak ( ) is a peak, 545 m high, which marks the southwestern end of the serrate ridge 1 mi northeast of Port Lockroy, Wiencke Island, in the Palmer Archipelago, Antarctica.
 It was probably first sighted in 1898 by the Belgian Antarctic Expedition under Gerlache, and was first charted by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, who named it for Jacques Jabet, boatswain of the expedition ship "Français".
