It also owns the tip of the Schoodic Peninsula and parts of sixteen smaller islands.

Roughly how high is Cadillac Mountain, the highest point on the US Atlantic coast?

Only about 1,500 feet up, Cadillac's summit still grows fragile sub-alpine plants, and visitors have trampled them so badly that areas are roped off while crews bring in soil to replant them.

Cadillac Mountain is the first place in the US to see the sunrise only during which part of the year?

Fall and winter, from October 7 to March 6, are when the low sun reaches Cadillac first, so the big summer dawn crowds are chasing a title the summit does not hold then.

Green Mountain was the name 19th-century tourists knew, when a cogwheel train hauled them up its slopes.

Virginia's Captain Samuel Argall led the raid, only months after he had abducted Pocahontas on the Potomac.

Which craft did Wabanaki artisans sell to Mount Desert Island's 19th-century tourists, now the pride of the local Abbe Museum?

What were Mount Desert Island's mid-1800s visitors called, who boarded cheaply with local fishermen and farmers?

Rusticators followed Hudson River School painters such as Thomas Cole and Frederic Church to the island, and by 1880 thirty hotels were competing for them.

Automobiles were banned from Mount Desert Island for years, and when the ban was lifted Rockefeller built a separate road network that stayed closed to cars.

The granite coping stones that edge the carriage roads as guard rails are nicknamed what?

Rockefeller's Teeth are the rough granite blocks lining the roads, and the volunteers who weed between them call the job flossing.

Beatrix Farrand drew up the planting plans at Rockefeller's request around 1930, using native plants to frame vistas and heal construction scars.

Which sun-loving trees replaced the spruce and fir Acadia's 1947 fire burned?

Birch and aspen seeded themselves across the sunlit burn, but they are short-lived, and the spruce and fir now sprouting in their shade may one day take the ground back.

Somes Sound, which nearly divides Mount Desert Island in two, is technically what kind of feature?

Fjard is the Scandinavian word for a drowned glacial valley smaller than a fjord, and Somes Sound was long billed as the East Coast's only fjord until geologists judged it too shallow and too well mixed.

Acadia's Bubble Rock, balanced on a mountain ledge, is an example of what?

A glacial erratic is a boulder that rode inside the ice and was dropped when it melted, and some of Acadia's travelled 20 miles or more before landing on a mountaintop.

How did the black stripes that cut across Acadia's pink granite at Schoodic Point form?

Magma filled cracks in the rock deep underground, after the granite had formed, and the black stripes were only exposed once erosion wore away everything above them.

Sea-floor mud and ash were buried, heated and squeezed into the Ellsworth Schist, and erosion and shifting plates later hauled the deep rock back up to the surface.

Geologists think the ice sheet that buried Mount Desert Island in the last ice age was about how thick?

About one mile of ice pressed the Maine coast down so far that the sea flooded in as the glacier melted, leaving old beaches stranded high above today's shore.

The ice-age sea clay that blankets the Maine coast around Acadia has yielded fossils of which large marine mammal?

Walruses swam here when the sea flooded the ice-weighted coast some 15,000 to 11,000 years ago, and the same clay gave up a mammoth that had washed out to sea.

When snow closes most of Acadia's 27-mile Park Loop Road to cars, which of these may legally take to it?

Snowmobiles may run the whole loop in winter, yet dog sleds are banned outright because park rules demand a six-foot leash.

Air forced out of a cavern at the inlet's end makes the clap, so on a calm day visitors hear almost nothing, while a storm swell can throw spray 40 feet high.

Which cliffside trail on Champlain Mountain is famous for its exposure and iron rungs?

The Precipice usually closes from late spring into summer so peregrine falcons can nest on its cliffs, and rangers set up telescopes in the parking lot below instead.

Sand Beach and Echo Lake are the park's two popular swimming beaches, while Jordan Pond is closed to swimmers because it supplies drinking water to a nearby village.

Which Acadia landmark is pictured on the park's 2012 America the Beautiful quarter?

Bass Harbor Head Light ranked among the park's most visited sights while it still belonged to the Coast Guard, which only handed the station over in 2020.

Afternoon tea on the lawn of Acadia's Jordan Pond House has come with which baked specialty since the 1890s?

Which pair of mountains forms the famous backdrop to the view across Jordan Pond?

The Bubbles were rounded by the same ice sheet that made the pond in front of them, which filled a valley dammed by a ridge of rubble the melting glacier left behind.

Acadia's plant life is unusually varied because the park straddles eastern deciduous woods and which other forest zone?

Boreal forest may not last here: as the climate warms, the spruce and fir that define it are expected to retreat north and leave more of the park to leafy hardwoods.

Which member of the deer family is only rarely seen in Acadia?

Moose need a great deal of room, so they seldom wander into the park, while white-tailed deer are easy to spot at dawn and dusk along the carriage roads.

About 4 million visits made 2025 a record even though the longest government shutdown in the park's history closed its visitor center at the start of October, one of its busiest months.

The Island Explorer buses that carried their 10 millionth Acadia passenger in 2024 ran on what fuel?

Friends of Acadia says its $13 million Acadia Trails Forever campaign created the first what in a national park?

Which Acadia mammal swaps a brown summer coat for a white winter one to match the seasons?

Snowshoe hare fur turns from brown to white for winter, so the animals are easiest to spot in between, when a half-changed coat matches neither the bare ground nor the snow.

More than a fifth of Acadia is classified as which kind of habitat?

Wetland covers over 20 percent of the park, from saltwater marshes to bogs and swamps, and beavers keep making more by damming streams.

Backcountry camping is ruled out everywhere in the park, so every tent has to go into one of its few campgrounds or a private one outside its borders.

Which landscape architect, a Harvard president's son, is credited with the original idea for Acadia?

Charles Eliot urged Maine to save its coast scenery in an article his father found among his papers after his death in 1897, and the father then founded the land trust that grew into the park.
