Thousand Islands – Frontenac Arch : ウィキペディア英語版
Thousand Islands – Frontenac Arch
The Thousand Islands – Frontenac Arch region, also known as the Frontenac Axis, connects the northern Canadian Shield with the Adirondack region. Hence, it provides an important biological corridor linking Adirondack Park with Algonquin Park.〔Keddy, Cathy J. 1995. The Conservation Potential of the Frontenac Axis: Linking Algonquin Park to the Adirondacks. Canadian Parks and Wilderness Society, Ottawa, Ontario. 59p.〕 The Thousand Islands are a chain of islands in the west end of the Saint Lawrence River, which have a distinctive flora and fauna, and which are a part of the biological corridor.
==Geology==
The bedrock is mostly gneiss, granite and marble, more than a billion years old.〔Eyles, Nick. Ontario Rocks. 2002. Three Billion Years of Environmental Change. Fitzhenry and Whiteside, Markham, Ontario. Chapter 9.〕 The Frontenac terrane is the youngest of the Ontario portions of the arch, dated at 1.2 billion years old.〔Eyles, Nick. Ontario Rocks. 2002. Three Billion Years of Environmental Change. Fitzhenry and Whiteside, Markham, Ontario. Figure 9.2A〕 These rocks were once part of the largest mountain chain the world has seen, a part of the ancient supercontinent of Rodinia. There is also a meteor crater near Holleford, where the shield meets the limestone plains of southeastern Ontario.〔Keddy, P.A. 2008. Earth, Water, Fire. An Ecological Profile of Lanark County. General Store Publishing House, Refrew, Ontario. p. 61-63.〕
