Boundary Waters in the context of "Old Northwest"

Height of Land Portage is a portage along the historic Boundary Waters route between Canada and the United States. Located at the border of the Canadian province of Ontario and the U.S. state of Minnesota, the path is a relatively easy crossing of the Laurentian Divide separating the Hudson Bay and Great Lakes-St. Lawrence watersheds.

The portage was used for centuries by Indigenous peoples for canoe travel, teaching it to European voyageurs and coureurs des bois who used it to access the fur trading posts in Rupert's Land. For many years the portage was part of an important route from Lower Canada to the interior of the North American continent. It became part of the boundary between British North America and the United States following the American Revolution and treaties delineating the border. In recognition of this history, the portage is on the U.S. National Register of Historic Places, and is a Minnesota State Historic Site.

The Northwest Territory, also known as the Old Northwest and formally known as the Territory Northwest of the River Ohio, was formed from part of the unorganized western territory of the United States after the American Revolution. Established in 1787 by the Congress of the Confederation through the Northwest Ordinance, it was the nation's first post-colonial organized incorporated territory.

At the time of its creation, the territory included all the land west of Pennsylvania, northwest of the Ohio River and east of the Mississippi River below the Great Lakes, and what later became known as the Boundary Waters. The region was ceded to the United States in the Treaty of Paris of 1783. Throughout the Revolutionary War, the region was part of the British Province of Quebec and the western theater of the war. It spanned all or large parts of six eventual U.S. states (Ohio, Indiana, Illinois, Michigan, Wisconsin, and the northeastern part of Minnesota). Reduced to present-day Ohio, and some additional lands north and east on July 4, 1800, it ceased to exist March 1, 1803, when the southeastern portion of the territory was admitted to the Union as the state of Ohio, and the remainder attached to Indiana Territory.

The Boundary Waters Canoe Area Wilderness (BWCAW or BWCA) comprises 1,090,000 acres (440,000 ha) of pristine forests, glacial lakes, and streams in the Superior National Forest. Located entirely within the U.S. state of Minnesota at the Boundary Waters, the wilderness area is under the administration of the United States Forest Service. Efforts to preserve the primitive landscape began in the 1900s and culminated in the Boundary Waters Canoe Area Wilderness Act of 1978. The area is a popular destination for canoeing, hiking, and fishing, and is the most visited wilderness in the United States.

The United States Lake Survey (USLS) was a hydrographic survey for the Great Lakes, New York Barge Canal, Lake Champlain and the Boundary Waters of the Canada–United States border between Minnesota and Ontario. The Survey's activities began on 31 March 1841, with the goal of surveying the Great Lakes. The Lake Survey was created within the United States Army Topographical Engineers (later the United States Army Corps of Engineers). Like the Commerce Department's United States Coast and Geodetic Survey, the Lake Survey had responsibility for the preparation and publication of nautical charts and other navigational aids. By 1882, the Survey had completed the original Congressional mandate, producing 76 charts, then disbanded. By 1901, the original survey and charting products required revision. The Lake Survey was reconstituted and its mission expanded. In addition to traditional survey, charting, and navigation information responsibilities, the Lake Survey was also responsible for studies on lake levels and associated river flow.

The Superior National Forest, part of the United States national forest system, is located in the Arrowhead Region of the state of Minnesota between the Canada–United States border and the north shore of Lake Superior. The area is part of the greater Boundary Waters region along the border of Minnesota and the Canadian province of Ontario, a historic and important thoroughfare in the fur trading and exploring days of New France and British North America.

Under the administration of the United States Forest Service, the Superior National Forest comprises over 3,900,000 acres (6,100 mi or 16,000 km) of woods and waters. The majority of the forest is multiple-use, including both logging and recreational activities such as camping, boating, and fishing. Slightly over a quarter of the forest is set aside as a wilderness reserve known as the Boundary Waters Canoe Area (BWCA), where canoers can travel along interconnected fresh waters near land as well as over historic portages once used by Native American tribes and First Nations people, but later also by European explorers and traders.

The Boundary Waters Canoe Area Wilderness Act of 1978 is a U.S. law (Pub.L. 95-495) that protects pristine forests, streams, and lakes in the Superior National Forest. Enactment of the law formally designated the Boundary Waters Canoe Area Wilderness (BWCA), which was previously known as the Boundary Waters Canoe Area. The main purpose of the law is to protect, preserve, and enhance the lakes, waterways and forested areas of the BWCA to enhance public enjoyment of the unique landscape and wildlife. It also establishes some form of management to maintain the area and places restrictions on logging, mining, and the use of motorized vehicles.

A bill to establish a protected wilderness area in the U.S. state of Minnesota at the Boundary Waters was first introduced in 1975 by United States Congressman Jim Oberstar and was a source of major controversy and debate. Topics of major concern were logging, mining, the use of snowmobiles and motorboats. After much debate, and passage by the U.S. House and Senate, the act was signed into law by President Jimmy Carter on October 21, 1978.
