Deer Island

Deer Island abuts the border with the US at the entrance to Passamaquoddy Bay on the south coast of New Brunswick. Long in dispute with the US, sovereignty over the island passed to NB in 1817. The name is probably descriptive. Fishing is the most important economic activity.

Partridge Island

Partridge Island is located in the Bay of Fundy, about 1 km from the shoreline and the city of Saint John, New Brunswick. The island was set aside as a quarantine station in 1785 and operated as such between 1830 and 1941. Many immigrants arriving to Canada by ship, including thousands of  Irish in 1847, were isolated on the island before being allowed to enter the country. This was done in an effort to prevent the spread of infectious diseases common on overcrowded vessels. In 1974, the Partridge Island quarantine station was designated a national historic site. Other important events are associated with the island, including the installation of the world’s first steam-operated fog alarm in 1859 (see also Robert Foulis).

Meteors, Meteorites and Impact Craters

The solar system contains many objects smaller than the planets (or their satellites) travelling in individual orbits about the SUN; space between the planets also contains myriad dust grains in the micron size range. Near Earth, dust concentrations are only a few hundred particles per cubic kilometre, but 35 000 to 100 000 t of extraterrestrial material enters the atmosphere annually, swept up by our planet from debris that is in its path or crosses its path.

Niagara River

The Niagara River, 58 km long, issues from Lake Erie and flows north over Niagara Falls to Lake Ontario. The river’s drainage area is about 684,000 km2, and its average flow at Queenston is 5,885 m3/s. The Niagara River forms part of the border between Canada and the United States.

Quill Lakes

The Quill Lakes are three connected saline lakes in southeastern Saskatchewan. They are located 150 km north of Regina and 152 km east of Saskatoon. From west to east the lakes are named Big Quill, Middle Quill (also known as Mud Lake) and Little Quill. Despite its name, at 181 km2 Little Quill is the second largest of the three lakes. Big Quill is the largest at 307 km2. The Quill Lakes’ elevation is 516 m.

Fraser River Lowland

The Fraser River Lowland is a triangular area in southwestern British Columbia. The eastern apex of the triangle is at Hope, about 160 km inland from the Strait of Georgia. From here, the lowland broadens to the west to a width of about 50 km. The international boundary between British Columbia and Washington State crosses the southwestern part of the lowland. The Coast Mountains form the northern boundary of the delta-lowland. The Fraser River Lowland is the largest area of level land with suitable agricultural soils in coastal British Columbia.

Okanagan Lake

Okanagan Lake is located in the southern interior of British Columbia and is the largest lake in the Okanagan Valley.

Great Bear Lake

Great Bear Lake is located in the Northwest Territories. With a surface area of 31,328 km2, Great Bear Lake is the largest lake located entirely inside Canadian borders. It is also the fourth largest in North America and the eighth largest in the world. Water flows out of the lake into the Great Bear River, then into the Mackenzie River. Other rivers connected to the lake include the Dease, Camsell and Johnny Hoe. Great Bear Lake is made up of five separate arms, each with their own names: Dease, McTavish, McVicar, Keith and Smith. (See also Largest Lakes in Canada.)

Lake Erie

Lake Erie, 25,700 km2 (including islands), of which 12,800 km2 lie in Canada, elevation 173.3 m; 388 km long, 92 km wide and 64 m deep. The shallowest of the five major Great Lakes (excluding Lake St. Clair), it receives most of its waters from Lake Huron via the Detroit River. Other major inflowing streams are the Maumee and Cuyahoga rivers in Ohio, and the Grand River in Ontario. The lake outflows through the Niagara River at Fort Erie, falling almost 100 m to Lake Ontario; more than 50 m of this drop occurs at Niagara Falls. It is also joined to Lake Ontario by the Welland Canal. (See also Largest Lakes in Canada.)

Manitoulin Island

Manitoulin Island, 2,765 km2, the largest island in the world located in a lake, is part of an archipelago at the top of Lake Huron straddling the Ontario-Michigan border. Its northern shore encloses the North Channel, which leads to the St. Mary's River at Sault Ste Marie. An extension of the Niagara Peninsula, Manitoulin Island has an irregular, rocky shoreline and many interior lakes.

Lake Ontario

Lake Ontario is 18,960 km2 (10,000 km2 in Canada), with a drainage area of 60,030 km2, an elevation of 75 m, a mean depth of 86 m (max 244 m), length 311 km and width 85 km. It is the smallest in surface area and most easterly of the Great Lakes and eighth-largest body of fresh water in North America. The lake receives most of its water supply from the other Great Lakes through the Niagara River and discharges into the St Lawrence River through the Kingston Basin at its northeast end. Other tributaries are the Genesee, Oswego and Black rivers in New York state and the Trent River in Ontario. (See also Largest Lakes in Canada.)

Lake Nipissing

Located in Northern Ontario, between the Ottawa River and Georgian Bay, Lake Nipissing is the third largest lake located entirely within the boundaries of Ontario. The lake spans 65 km in an east–west direction and drains into Georgian Bay via the French River. Its name derives from an Ojibwa word meaning "little water," likely a comparison to the nearby Great Lakes, which were important trade routes for the Nbisiing (Nipissing), the First Nation indigenous to this region. Fishing is a popular activity on the lake both commercially and recreationally. Unfortunately, walleye, the lake’s dominant fish species, has declined drastically since the 1980s as a result of overfishing and ecosystem changes.

Rocky Mountain Trench

The Rocky Mountain Trench is a long and deep valley extending approximately 1,500 km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory. Its predominantly flat floor is 3–20 km wide and ranges in elevation between 600 m and 1,000 m above sea level. With walls made of sedimentary, volcanic and igneous rock, the Trench is sometimes referred to as the “Valley of a Thousand Peaks” because of the towering mountain ranges on either side: the Rocky Mountains to the east and the Columbia, Omineca and Cassiar mountains to the west. Humans have relied on the rich resources provided by this distinctive landscape from pre-colonial times to the present.

Great Lakes

The Great Lakes are the largest group in a chain of large lakes (including WinnipegAthabascaGreat Slave and Great Bear) that lies along the southern boundary of the Canadian Shield. From west to east the Great Lakes comprise lakes Superior, Michigan (entirely in the US), HuronSt. ClairErie and Ontario. They have a total area of approximately 244,100 km2 and drop from 183 m above sea level at Lake Superior to 74 m at Lake Ontario — the most dramatic drop occurring at Niagara Falls. Lake St Clair, while not properly a “great lake,” is considered part of this Laurentian chain.

Lake Huron is the second largest of the Great Lakes and fifth-largest lake in the world (see also Largest Lakes in Canada). In Canada, the Lake Huron is part of the traditional territories of the Tionontati (Petun)NeutralHuron-Wendat and AnishinaabeSamuel de Champlain visited Georgian Bay and Lake Huron with the French scout Étienne Brûlé in 1615.
