The State of Maine ( /ˈmeɪn/ (help·info)) is a state in the New England region of the northeastern United States, bordering the Atlantic Ocean to the southeast, New Hampshire to the southwest, and the Canadian provinces of Quebec to the northwest and New Brunswick to the northeast. Maine is the northernmost portion of New England and is the easternmost state in the contiguous United States. It is known for its scenery — its jagged, mostly rocky coastline, its low, rolling mountains, and its heavily forested interior — as well as for its seafood cuisine, especially lobsters and clams. The original inhabitants of the territory that is now Maine were Algonquian-speaking peoples. The first European settlement in Maine was in 1604 by a French party. The first English settlement in Maine, the short-lived Popham Colony, was established by the Plymouth Company in 1607. A number of English settlements were established along the coast of Maine in the 1620s, although the rugged climate, deprivations, and Indian attacks wiped out many of them over the years. As Maine entered the 18th century, only a half dozen settlements still survived. American and British forces contended for Maine's territory during the American Revolution and the War of 1812. Maine was an exclave of Massachusetts until 1820, when as a result of the growing population, it became the 23rd state on March 15 under the Missouri Compromise. There is no definitive answer for the origin of the name Maine. The state legislature in 2001 adopted a resolution establishing Franco-American Day, which stated that the state was named after the ancient French province of Maine.[4] Other theories mention earlier places with similar names, or claim it is a nautical reference to the mainland.[5] Whatever the origin, the name was fixed in 1665 when the King's Commissioners ordered that the "Province of Maine" be entered from then on in official records.[6] To the south and east is the Atlantic Ocean and to the north and northeast is New Brunswick, a province of Canada. The Canadian province of Quebec is to the northwest. Maine is both the northernmost state in New England and the largest, accounting for nearly half the region's entire land area. Maine also has the distinction of being the only state to border just one other state (New Hampshire to the west). The municipalities of Eastport and Lubec are, respectively, the easternmost city and town in the United States. Estcourt Station is Maine's northernmost point and also the northernmost point in the New England region of the United States. (For more information see extreme points of the United States). Maine's Moosehead Lake is the largest lake wholly in New England (Lake Champlain being located between Vermont and New York). A number of other Maine lakes, such as South Twin Lake, are described by Thoreau. Mount Katahdin is both the northern terminus of the Appalachian Trail, which extends to Springer Mountain, Georgia, and the southern terminus of the new International Appalachian Trail which, when complete, will run to Belle Isle, Newfoundland and Labrador. Maine also has several unique geographical features. Machias Seal Island and North Rock, off its easternmost point, are claimed by both the U.S. and Canada and are within one of four areas between the two countries whose sovereignty is still in dispute, but is the only one of the disputed areas containing land. Also in this easternmost area is the Old Sow, the largest tidal whirlpool in the Western Hemisphere. Maine is the most sparsely populated state east of the Mississippi River. It is called the Pine Tree State; ninety percent of its land is forested. In the forested areas of the interior lies much uninhabited land, some of which does not have formal political organization into local units (a rarity in New England). The Northwest Aroostook, Maine unorganized territory in the northern part of the state, for example, has an area of 2,668 square miles (6,910 km2) and a population of 27, or one person for every 100 square miles (260 km2). Maine is equally well known for its ocean scenery, with almost 3,500 miles (5,600 km) of shoreline.[7] West Quoddy Head is the easternmost piece of land in the contiguous 48 United States. Along the famous rock-bound coast of Maine are lighthouses, beaches, fishing villages, and thousands of offshore islands, including the Isles of Shoals, which straddle the New Hampshire border. Jagged rocks and cliffs and thousands of bays and inlets add to the rugged beauty of Maine's coast. Just inland, by contrast, are lakes, rivers, forests, and mountains. This visual contrast of forested slopes sweeping down to the sea has been aptly summed up by American poet Edna St. Vincent Millay of Rockland and Camden, Maine in "Renascence": More prosaic geologists describe this type of landscape as a drowned coast, where a rising sea level has invaded former land features, creating bays out of valleys and islands out of mountain tops.[8] A rise in the elevation of the land due to the melting of heavy glacier ice caused a slight rebounding effect of underlying rock; this land rise, however, was not strong enough to eliminate all the effect of the rising sea level and its invasion of former land features. The noted American ecologist Rachel Carson did much of her research at one of the Maine seacoast's most characteristic features, a tide pool for her classic "The Edge of the Sea." The spot where she conducted observations is now preserved as the Rachel Carson Salt Pond Reserve at Pemaquid Point. George Lorenzo Noyes, known as the thoreauvian of Maine is a noted state naturalist, mineralogist, development critic, writer and landscape artist. He lived a devout wilderness lifestyle in the mountains of Norway, Maine, expressing in his paintings his spiritual reverence for nature and writing of the values of a simple life of sustainable living. Harvard Quarry at the summit of Noyes Mountain, named in his honor, in Greenwood, provides an excellent panoramic view and is a popular destination for rock and mineral collectors. Much of Maine's geography was created by heavy glacial activity at the end of the last ice age. Prominent glacial features include Somes Sound and Bubble Rock. Carved by glaciers, Somes Sound is considered to be the only fjord on the eastern seaboard and reaches depths of 175 feet (50 m). The extreme depth and steep drop-off allow large ships to navigate almost the entire length of the sound. These features also have made it attractive for boat builders, such as the prestigious Hinckley Yachts. Bubble Rock is what is known as a "glacial erratic" and is a large boulder perched on the edge of Bubble Mountain in Acadia National Park. By analyzing the type of granite, geologists were able to discover that glaciers carried Bubble Rock to its present location from the town of Lucerne, Maine — 30 miles away. Acadia National Park is the only national park in New England. Areas under the protection and management of the National Park Service include:[9] Maine experiences a humid continental climate (Köppen climate classification Dfb), with warm (although generally not hot), humid summers. Winters are cold and snowy throughout the state, and are especially severe in the northern parts of Maine. Coastal areas are moderated somewhat by the Atlantic Ocean. Daytime highs are generally in the 75–80 °F (24–27 °C) range throughout the state in July, with overnight lows in the high 50s°F (around 15 °C). January temperatures range from highs near 32 °F (0 °C) on the southern coast to overnight lows below 0 °F (−18 °C) in the far north. Maine is generally safe from hurricanes and tropical storms. By the time they reach the state, many have become extratropical and few hurricanes have made landfall in Maine. Maine has fewer days of thunderstorms than any other state east of the Rockies, with most of the state averaging less than 20 days of thunderstorms a year. Tornadoes are rare in Maine with the state averaging fewer than two per year, mostly occurring in the southern part of the state.[10] In January 2009, a new record low temperature for the state was set at −50 °F, tying the New England record.[11] The state's record high temperature is 105 °F, set in July 1911.[12] The original inhabitants of the territory that is now Maine were Algonquian-speaking Wabanaki peoples including the Abenaki, Passamaquoddy, and Penobscots. The first European settlement in Maine was in 1604 by a French party that included Samuel de Champlain, the noted explorer. The French named the entire area, including the portion that later became the State of Maine, Acadia. The first English settlement in Maine was established by the Plymouth Company at Popham in 1607, the same year as the settlement at Jamestown, Virginia. Both colonies were predated by the Roanoke Colony by 22 years. Because the Popham Colony did not survive the harsh Maine winters and the Roanoke Colony was lost, Jamestown enjoys the distinction of being regarded as America's first permanent English-speaking settlement. The coastal areas of western Maine first became the Province of Maine in a 1622 land patent. Eastern Maine north of the Kennebec River was more sparsely settled and was known in the 17th century as the Territory of Sagadahock. A second settlement was attempted at a place called York, now Portland, in 1623 by English explorer and naval Captain Christopher Levett, granted 6,000-acres by King Charles I of England.[13] That settlement also failed. The province within its current boundaries became part of Massachusetts Bay Colony in 1652. Maine was much fought over by the French and English during the 17th and early 18th centuries. After the defeat of the French in the 1740s, the territory from the Penobscot River east fell under the nominal authority of the Province of Nova Scotia, and together with present day New Brunswick formed the Nova Scotia county of Sunbury, with its court of general sessions at Campobello. American and British forces contended for Maine's territory during the American Revolution and the War of 1812, and British forces occupied eastern Maine in both conflicts.[14] The treaty concluding revolution was ambiguous about Maine's boundary with British North America. The territory of Maine was confirmed as part of Massachusetts when the United States was formed, although the final border with British territory was not established until the Webster-Ashburton Treaty of 1842.
