Wisconsin glaciationThe Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America.
Niagara FallsNiagara Falls (naɪˈæɡərə) is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York.
Illinois RiverThe Illinois River (Inoka Siipiiwi) is a principal tributary of the Mississippi River and is approximately long. Located in the U.S. state of Illinois, the river has a drainage basin of . The Illinois River begins with the confluence of the Des Plaines and Kankakee rivers in the Chicago metropolitan area, and it generally flows to the southwest across Illinois, until it empties into the Mississippi near Grafton, Illinois. Its drainage basin extends into southeastern Wisconsin, northwestern Indiana, and a very small area of southwestern Michigan in addition to central Illinois.
Chicago RiverThe Chicago River is a system of rivers and canals with a combined length of that runs through the city of Chicago, including its center (the Chicago Loop). Though not especially long, the river is notable because it is one of the reasons for Chicago's geographic importance: the related Chicago Portage is a link between the Great Lakes and the Mississippi River Basin, and ultimately the Gulf of Mexico. The river is also noteworthy for its natural and human-engineered history.
Chinook salmonThe Chinook salmon ʃɪˈnʊk (Oncorhynchus tshawytscha) is the largest and most valuable species of Pacific salmon in North America, as well as the largest in the genus Oncorhynchus. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name chavycha (чавыча).
Erie peopleThe Erie people (also Eriechronon, Riquéronon, Erielhonan, Eriez, Nation du Chat) were Indigenous people historically living on the south shore of Lake Erie. An Iroquoian group, they lived in what is now western New York, northwestern Pennsylvania, and northern Ohio before 1658. Their nation was decimated in the mid-17th century by five years of prolonged warfare with the powerful neighboring Iroquois for helping the Huron in the Beaver Wars for control of the fur trade.
Yellow perchThe yellow perch (Perca flavescens), commonly referred to as perch, striped perch, American perch, American river perch or preacher is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch (Perca fluviatilis); and is sometimes considered a subspecies of its European counterpart.
Welland CanalThe Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario, and Port Colborne on Lake Erie, and was erected because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.

Manitoulin IslandManitoulin Island (ˌmænəˈtuːlᵻn ) is an island in Lake Huron, located within the borders of the Canadian province of Ontario, in the bioregion known as Laurentia. With an area of , it is the largest lake island in the world, large enough that it has over 100 lakes itself.
