Q 01Channel Islands National Park lies off the coast of which US state?
California
California's park islands sit only a boat ride from the mainland, yet thousands of years of isolation left them with animals and plants found nowhere else on Earth.
Q 02Which of these Channel Islands lies outside the national park?
Santa Catalina
Santa Catalina is not part of the park: since 1975, when chewing-gum heir Philip Wrigley deeded over his family's land, a private land trust has controlled nearly 90 percent of the island.
Q 03Which classic children's novel was inspired by the 'Lone Woman' who lived alone on San Nicolas Island for 18 years?
Island of the Blue Dolphins
Island of the Blue Dolphins retells her story: left behind when her people were taken to the mainland in 1835, she survived alone until 1853, living in a hut of whale bones and brush.
Q 04Which nonprofit owns the western three-quarters of Santa Cruz Island?
The Nature Conservancy
The Nature Conservancy owns the western 76 percent: it took over the island's main ranch in 1987, wound up the livestock business, and handed the Park Service 8,500 acres in 2000.
Q 05Which two islands were first protected as a national monument in 1938?
Anacapa and Santa Barbara
Anacapa and Santa Barbara became Channel Islands National Monument by Franklin Roosevelt's proclamation in April 1938; Santa Cruz, Santa Rosa and San Miguel were added when Congress made it a national park.
Q 06What has ringed Channel Islands National Park since 1980?
Marine sanctuary
A national marine sanctuary now protects about 1,470 square miles of sea around the park islands; it was set up partly out of alarm at the 1969 oil spill in the channel.
Q 07The endemic island fox, found on six of the Channel Islands, evolved from which larger mainland ancestor?
Grey fox
The grey fox reached the islands thousands of years ago, possibly carried over by people, and its descendants shrank by a third to about the size of a housecat.
Q 08What nearly wiped out San Miguel's island foxes in the 1990s, leaving just 15 animals?
Predation by golden eagles
Golden eagles colonised the islands after DDT wiped out the fish-eating bald eagles, and feral pigs gave them year-round prey; predation by golden eagles nearly wiped out the foxes, and four subspecies were listed as endangered in 2004.
Q 09Why is there no island fox on Anacapa?
It has no reliable fresh water
It has no reliable fresh water, so the foxes that reached Anacapa could not persist there, while the three larger islands next door each kept a subspecies of their own.
Q 10Which bird species lives only on Santa Cruz Island and nowhere else on Earth?
Island scrub jay
The island scrub jay is larger and brighter than its mainland cousin, with a stout bill for the thick-shelled acorns it buries each fall and digs up to eat months later.
Q 11The Channel Islands are nicknamed North America's answer to which islands?
The Galápagos
The Galápagos comparison rests on isolation: the islands were never joined to the mainland, so the few animals and plants that made the crossing evolved into forms found nowhere else.
Q 12The islands' pygmy mammoth descended from which giant mainland species that swam the channel?
Columbian mammoth
The Columbian mammoth stood about twice as tall on the mainland; marooned on islands where food grew scarce as the seas rose, its descendants shrank into a pygmy species.
Q 13What name is given to the large island that the four northern Channel Islands formed during the last ice age?
Santa Rosae
Q 21What was Anacapa's Chumash name, Anyapax, said to mean?
Mirage or illusion
Anyapax means 'mirage or illusion': seen through summer fog or afternoon heat the island seems to change shape, and it is really three separate islets rather than one.
Q 22Which wave-carved landmark off East Anacapa is a symbol of Channel Islands National Park?
Arch Rock
Arch Rock is a 40-foot natural bridge that waves cut through Anacapa's volcanic rock; James McNeill Whistler, later a famous painter, etched it for a US Coast Survey chart in 1854.
Q 23What did the federal government finish on East Anacapa in 1932, the last major one built on the US West Coast?
A lighthouse
Santa Rosae formed when ice-age seas dropped and joined the four northern islands; even then a few miles of open water cut it off from the mainland, so its mammoths had to swim out.
Q 14What made the pygmy mammoth skeleton found on Santa Rosa Island in 1994 a landmark?
It was nearly complete
It was nearly complete: when the Park Service called in scientists to identify some exposed bones, they turned out to be the first pygmy mammoth skeleton found virtually whole.
Q 15Arlington Springs Man's ice-age bones on Santa Rosa Island are evidence that the first Americans already had what?
Boats
Boats were the only way there: the islands were never joined to the mainland, so a man who died on one at the end of the ice age must have crossed open water.
Q 16Which large seabird, nearly wiped out by DDT, has its biggest US West Coast breeding colony on West Anacapa?
Brown pelican
Brown pelicans almost stopped raising chicks on West Anacapa around 1970, because DDT washing into the sea thinned their eggshells; the colony recovered after the pesticide was banned.
Q 17Where did the last of the island Chumash settle when they left for the mainland by the 1820s?
Spanish missions
Spanish missions on the mainland took in the last islanders, whose villages had emptied as newcomers' diseases spread and their food supplies were depleted.
Q 18The Chumash crossed the channel in a distinctive sewn-plank canoe called what?
Tomol
The tomol was made from redwood logs that drifted down the coast, split into planks and sewn together; the craft lapsed in the 1830s until a new Brotherhood of the Tomol built Helek in 1976.
Q 19Which European explorer first recorded the islands in 1542?
Juan Rodríguez Cabrillo
Juan Rodríguez Cabrillo, sailing for Spain, reached the islands in October 1542 on the first European voyage along the coast north of Baja; he died of an injury there in January 1543.
Q 20Which British navigator named San Miguel Island on his 1793 chart, borrowing from a Spanish map?
George Vancouver
George Vancouver's 1793 expedition standardized the names of the Channel Islands, taking San Miguel from a Spanish chart; earlier Spanish visitors had each given the islands names of their own.
A lighthouse came late to Anacapa: wrecks piled up on its rocks before an unmanned acetylene beacon went up in 1912, and the full light station followed only in 1932.
Q 24Which invasive mammal was eradicated from Anacapa in 2001-02 to protect nesting seabirds?
Black rat
Black rats, also called ship rats, ate seabird eggs and chicks and severely depleted the island's Scripps's murrelets, until the two-year eradication left Anacapa rat-free.
Q 25Which island, about one square mile in size, is the smallest of the eight Channel Islands?
Santa Barbara
Santa Barbara Island covers just 639 acres, yet families farmed and grazed it in the early 1900s; its native plants and wildlife have been recovering since the ranching ended.
Q 26What does the ranger-led hike to Point Bennett on San Miguel reward walkers with?
Thousands of elephant seals and sea lions
Thousands of elephant seals and sea lions haul out at Point Bennett; the elephant seals are a comeback story, hunted so hard for their blubber that by the 1880s the species was presumed extinct.
Q 27Santa Rosa Island is one of only two places in the world where which rare tree grows wild?
Torrey pine
The Torrey pine grows wild only on Santa Rosa Island and near San Diego, the last remnants of a forest that was widespread in the ice age; summer fog gives the trees just enough moisture.
Q 28Oilman Edwin Stanton bought most of Santa Cruz Island in 1937 and replaced its sheep with which livestock?
Cattle
Cattle made more sense when Stanton took over, because the state's beef industry was growing fast; his 54,000-acre island ranch became the largest in its county.
Q 29Painted Cave on Santa Cruz Island, one of the world's largest sea caves, gets its colours from what?
Rocks, lichens and algae
Rocks, lichens and algae colour the walls naturally, with no paint involved; the entrance is tall enough for a large boat to sail inside.
Q 30What record did the 1969 blow-out that oiled the islands' beaches set at the time?
Largest oil spill in US waters
Largest oil spill in US waters at the time: oil reached beaches from the mainland to the Channel Islands and killed thousands of seabirds, though two later spills have since dwarfed it.
