Question: The Penetanguishene Bay Purchase, registered as Crown Treaty Number Five, was signed May 22, 1798 , it purchased the lands around Matchedash Bay on Lake Huron, one of the five Great Lakes, of which continent?
Context: Lake Michigan is one of the five Great Lakes of North America and the only one located entirely within the United States.  The other four Great Lakes are shared by the U.S. and Canada.  It is the second-largest of the Great Lakes by volume and the third-largest by surface area, after Lake Superior and Lake Huron (and is slightly smaller than the U.S. state of West Virginia).  To the east, its basin is conjoined with that of Lake Huron through the wide Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake. The Great Lakes (French: "les Grands-Lacs" ), also called the Laurentian Great Lakes and the Great Lakes of North America, are a series of interconnected freshwater lakes located primarily in the upper mid-east region of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence River.  Consisting of Lakes Superior, Michigan, Huron (or Michigan–Huron), Erie, and Ontario, they form the largest group of freshwater lakes on Earth by total area, and second largest by total volume containing 21% of the world's surface fresh water by volume.  The total surface is 94250 sqmi , and the total volume (measured at the low water datum) is 5439 cumi .  Due to their sea-like characteristics (rolling waves, sustained winds, strong currents, great depths, and distant horizons) the five Great Lakes have also long been referred to as "inland seas".  Lake Superior is the second largest lake in the world by area, and Lake Michigan is the largest lake that is entirely within one country.  The southern half of the Great Lakes is bordered by the Great Lakes Megalopolis. The Lake Simcoe–Lake Huron Purchase, registered as Crown Treaty Number Sixteen, was signed November 18, 1815 between the Ojibwa and the government of Upper Canada.  It purchased a large portion of the lands between Lake Simcoe and Lake Huron, including all of the territory upon which the Penetanguishene Road had recently been cut. The Great Lakes Storm of 1913, historically referred to as the "Big Blow," the "Freshwater Fury," or the "White Hurricane," was a blizzard with hurricane-force winds that devastated the Great Lakes Basin in the Midwestern United States and the province of Ontario in Canada from November 7 through November 10, 1913.  The storm was most powerful on November 9, battering and overturning ships on four of the five Great Lakes, particularly Lake Huron.  Deceptive lulls in the storm and the slow pace of weather reports contributed to the storm's destructiveness. Point Clark Lighthouse is located on in a beach community, Point Clark, Ontario, near a point that protrudes into Lake Huron.  Built between 1855 and 1859 under the instructions of the Board of Works, Canada West, it is one of the few on the Great Lakes to be made primarily from stone.  It is one of the Imperial Towers, a group of six nearly identical towers built by contractor John Brown for the "Province of Canada" (Canadian government) on Lake Huron and Georgian Bay, all completed by 1859.  The location for the Point Clark lighthouse was selected to warn sailors of the shoals (sandbars) 2 mi off the Lake Huron coast.  It is still functioning as an automated light.  A restoration that eventually exceeded $2.3 million started in 2011 and the facility reopened for tourism in June 2015. The following is a list of Michigan islands in Lake Huron.  Lake Huron is the second largest of the Great Lakes (after Lake Superior).  With a surface area of 23,010 mi² (59,596 km²), it ranks as the third largest fresh water lake in the world.  Michigan is the only U.S. state to border Lake Huron, while the portion of the lake on the other side of the international border belongs to the Canadian province of Ontario.  For the islands belonging to Ontario, see the List of Ontario islands in Lake Huron.  This article also does not include islands that are part of the St. Marys River. Matchedash Bay is a bay and Ramsar wetland in Simcoe County in Central Ontario, Canada.  It is the "final inland extension of Severn Sound" on Lake Huron's Georgian Bay, and is "situated at the interface between the Saint Lawrence Lowlands and the Canadian Shield ".  It exhibits geologically unique features at the junction of the Canadian Shield and southern Ontario limestone.  Wetland habitats in Matchedash Bay are varied, and include swamps, fens, cattail marshes, wet meadows and beaver ponds.  Other features include "permanent freshwater lakes; upland hardwood forest, agricultural lands, native grass meadows and a unique, coniferous wetland forest". Lake Huron (French: "Lac Huron" ) is one of the five Great Lakes of North America.  Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as its westerly counterpart, to which it is connected by the 5 mi , 20 fathom Straits of Mackinac.  It is shared on the north and east by the Canadian province of Ontario and on the south and west by the state of Michigan in the United States.  The name of the lake is derived from early French explorers who named it for the Huron people inhabiting the region. The Penetanguishene Bay Purchase, registered as Crown Treaty Number Five, was signed May 22, 1798 between the Chippeway and the government of Upper Canada.  It purchased the lands around Matchedash Bay on Lake Huron for a price of one hundred and one pounds in Quebec currency. The Huron Tract Purchase also known as the Huron Block, registered as Crown Treaty Number 29, is a large area of land in southwestern Ontario bordering on Lake Huron to the west and Lake Erie to the east.  The area spans the counties of Huron, Perth, Middlesex and present day Lambton County, Ontario in the Province of Ontario.
