The Province of New Hampshire was an English colony and later a British province in New England. It corresponds to the territory between the Merrimack and Piscataqua rivers on the eastern coast of North America. It was named after the English county of Hampshire in southern England by Captain John Mason in 1629, its first named proprietor. In 1776, the province established an independent state and government, the State of New Hampshire, and joined with twelve other colonies to form the United States.
The Province of Maine refers to any of the various English colonies established in the 17th century along the northeast coast of North America, within portions of the present-day U.S. states of Maine, New Hampshire, and Vermont, and the Canadian provinces of Quebec and New Brunswick. It existed through a series of land patents made by the kings of England during this era, and included New Somersetshire, Lygonia, and Falmouth. The province was incorporated into the Massachusetts Bay Colony during the 1650s, beginning with the formation of York County, Massachusetts, which extended from the Piscataqua River to just east of the mouth of the Presumpscot River in Casco Bay. Eventually, its territory grew to encompass nearly all of present-day Maine.
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf. In a narrower sense, the term is often used as a synonym for the territorial sea.
The Piscataqua River is a 12-mile-long (19 km) tidal river forming the boundary of the U.S. states of New Hampshire and Maine from its origin at the confluence of the Salmon Falls River and Cochecho River to the Atlantic Ocean. The drainage basin of the river is approximately 1,495 square miles (3,870 km2), including the subwatersheds of the Great Works River and the five rivers flowing into Great Bay: the Bellamy, Oyster, Lamprey, Squamscott, and Winnicut.
The Canada–United States border is the longest international border in the world. The boundary is 8,891 km (5,525 mi) long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP).

The geology of New Hampshire is similar to that of the rest of New England in comprising a series of metamorphosed sedimentary and volcanic rocks of Late Proterozoic to Devonian age, intruded by many plutons and dikes ranging in age from Late Proterozoic to early Cretaceous. New Hampshire is known as "the Granite State", but less than half is underlain by granite; much of it is schist or gneiss, both of which are metamorphic rocks.
