North Shore Highlands : ウィキペディア英語版 | North Shore Highlands
The North Shore Highlands are a physiographic and ecological region of the U.S. state of Minnesota in central North America. They were formed by a variety of geologic processes, but are principally composed of rock created by magma and lava from a rift about 1.1 billion years ago, which rock formations are interspersed with and overlain by glacial deposits. Their ecology derives from these origins, with thin, rocky soils supporting flora and fauna typical of their northern, inland location. ==Geography== The North Shore Highlands are part of what once was called the Cabotian Mountains, a name applied to the highlands north of Lake Superior. They are bounded on the south by the North Shore of Lake Superior, from which they rise in rock formations ranging from gentle slopes to sheer cliffs. They extend from the Dalles of the Saint Louis River in Jay Cooke State Park on the west near Thomson, Minnesota, to the Grand Portage Highlands in the Grand Portage Indian Reservation at the easternmost extremity of the state. Between these anchors are cliffs along the shore such as Silver Creek Cliff, Split Rock, Palisade Head, and Shovel Point; the Sawtooth Range, also lakeside in the central part of the uplands; and the inland Misquah Hills to the east, containing Eagle Mountain, the highest point in Minnesota.
