Thousand Islands – Frontenac Arch Thousand Islands – Frontenac Arch The Thousand Islands – Frontenac Arch region or the Frontenac Axis is an exposed strip of Precambrian rock in Canada and the United States that links the Canadian Shield from Algonquin Park with the Adirondack Mountain region in New York, an extension of the Laurentian mountains of Québec. The Algonquin to Adirondacks region, which includes the Frontenac Axis or Arch, is a critical linkage for biodiversity and resilience, and one with important conservation potential. The axis separates the St. Lawrence Lowlands and the Great Lakes Lowlands. It has many distinctive plant and animal species. It
Thousand Islands (Cocoa Beach) deposit include the existence of a layer of plain sand (often containing terrestrial vegetation debris) sandwiched between sediments containing numerous small bivalve mollusc shells that are indicative of deposition in a normal lagoon environment. This uneven sand layer lacking shells suggests an interruption in the normal accretion of benthic sediments by a rapid deposition of dune material being washed in by severe wave action. There are about 100 islands in the Thousand Islands, The actual number of islands is meaningless due to the inundation of many areas during seasonal high water during summer. The relatively low topography and rising water
