The Boundary Waters Canoe Area Wilderness (BWCAW or BWCA), is a wilderness area within the Superior National Forest in northeastern Minnesota (USA) under the administration of the U.S. Forest Service. A mixture of north woods forests and glacial lakes and streams, the BWCAW's preservation as a primitive wilderness began in the 1900s and culminated in the Boundary Waters Canoe Area Wilderness Act of 1978. It is a popular destination for both canoeing and fishing on its many lakes and is the most visited wilderness in the United States. == Geography == The BWCAW extends along of the U.S.–Canadian border in the Arrowhead Region of Minnesota. The combined region of the BWCAW, the Superior National Forest, the Voyageurs National Park and the Canadian Quetico and La Verendrye Provincial Park to the north make up a large area of contiguous wilderness lakes and forests called the "Quetico-Superior country", or simply the Boundary Waters. Lake Superior lies to the east of the Boundary Waters.〔(【引用サイトリンク】url=http://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprd3799760.pdf )〕 , nearly 20% of the BWCAW's total area, is water: within its borders are over 1,100 lakes and hundreds of miles of rivers and streams. Much of the other 80% is forest. The BWCAW is the largest remaining area of uncut forest in the eastern portion of the United States.〔 The Laurentian Divide between the Great Lakes and Hudson Bay watersheds runs northeast–southwest through the east side of the BWCAW, following the crest of the Superior Upland and Gunflint Range. The crossing of the divide at Height of Land Portage was the occasion for ceremony and initiation rites for the fur-trading Voyageurs of the 18th and early 19th centuries. The wilderness also includes the highest peak in Minnesota, Eagle Mountain (), part of the Misquah Hills.〔 Located around the perimeter of the BWCAW are six ranger stations: in Cook, Aurora, Ely, Isabella, Tofte and Grand Marais. The two nearby communities with most visitor services are Ely and Grand Marais.〔 Several historic roads such as the Gunflint Trail, Echo Trail (County Road 116) and Fernberg Road (County Road 18) allow access to the many wilderness entry points.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boundary Waters Canoe Area Wilderness」の詳細全文を読む スポンサード リンク
