Queenston Shale
The Queenston Formation is a geological formation of Upper Ordovician age (Maysvillian to Richmondian Stage), which outcrops in Ontario, Canada (along the northern and eastern flanks of the Niagara Escarpment, as well as east of Ottawa) and New York, United States (just south of Lake Ontario). A typical outcrop of the formation is exposed at Bronte Creek just south of the Queen Elizabeth Way. The formation is a part of the Queenston Delta clastic wedge, formed as an erosional response to the Taconic Orogeny. Lithologically, the formation is dominated by red and grey shales with thin siltstone, limestone and sandstone interlayers. As materials, comprising the clastic wedge, become coarser in close proximity to the Taconic source rocks, siltstone and sandstone layers are predominant in New York. Structure and stratigraphy The formation is wedge-shaped, thick (up to below Lake Erie), and laterally extensive, outcropping from Western New York to Cabot Head. It thins from southeast ...

Cheltenham Badlands
The Cheltenham Badlands are in Caledon, Ontario, on the southeast side of Olde Base Line Road, between Creditview and Chinguacousy Roads. The site occupies an area of approximately 0.4 square kilometers and features exposed and highly eroded Queenston shale. The Cheltenham Badlands are a significant educational site due to the readily visible geologic processes and the red colour and the unique topography of the exposed shale make this a popular tourist site. The site is a Provincial Earth Sciences Area of Natural and Scientific Interest (ANSI) since it is considered one of the best examples of "badlands topography" in Ontario. Background The Cheltenham Badlands, sometimes referred to as the Chinguacousy Badlands, the Red Clay Hills, the Caledon Badlands, or the Inglewood Badlands, are approximately 3.8 km west of highway 10 on Olde Base Line Road near the villages of Inglewood and Cheltenham. The northern boundary of the badlands site is Peel Regional Road 12 (Olde Base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Queenston Delta
The Queenston Delta is a 300-mile-wide clastic wedge of sediment deposited over what is now eastern North America during the late Ordovician period due to the erosion of mountains created during the Taconic orogeny. The wedge is thickest in a band running from New York State to Quebec Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirtee ... and extends from the Catskill mountains to Lake Huron.

Queen Elizabeth Way
The Queen Elizabeth Way (QEW) is a 400-series highway in the Canadian province of Ontario linking Toronto with the Niagara Peninsula and Buffalo, New York. The freeway begins at the Peace Bridge in Fort Erie and travels around the western end of Lake Ontario, ending at Highway 427 in Toronto. The physical highway, however, continues as the Gardiner Expressway into downtown Toronto. The QEW is one of Ontario's busiest highways, with an average of close to 200,000 vehicles per day on some sections. Major highway junctions are at Highway 420 in Niagara Falls, Highway 405 in Niagara-on-the-Lake, Highway 406 in St. Catharines, the Red Hill Valley Parkway in Hamilton, Highway 403 and Highway 407 in Burlington, Highway403 at the Oakville–Mississauga boundary, and Highway427 in Etobicoke. Within the Regional Municipality of Halton the QEW is signed concurrently with Highway403. The speed limit is throughout most of its length, with the exc ...

Bronte Creek
Bronte Creek is a waterway in the Lake Ontario watershed of Ontario Canada. It runs through Hamilton and Halton Region, with its source near Morriston (south of the intersection of Highway 6 and Highway 401), passing Bronte Creek Provincial Park, on its way to Lake Ontario at Bronte Harbour in Oakville, where the creek is also known as Twelve Mile Creek. Bronte takes its name from the title of the Duke of Bronté held by Horatio Nelson. Bronte Creek in Ojibwe is "Eshkwesing-ziibi", "Esqui-sink", "Eshkwessing", "ishkwessin", and "Asquasing" ("that which lies at the end"). Geology Just south of the Queen Elizabeth Way at the Bronte Road exit, the creek has exposed an outcrop of Queenston Formation red shale with narrow, greenish layers of calcareous sandstone and silty bioclastic carbonate.

Lake Ontario
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York. The Canada–United States border spans the centre of the lake. The Canadian cities of Toronto, Kingston, Mississauga, and Hamilton are located on the lake's northern and western shorelines, while the American city of Rochester is located on the south shore. In the Huron language, the name means "great lake". Its primary inlet is the Niagara River from Lake Erie. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River, comprising the eastern end of the Saint Lawrence Seaway. The Moses-Saunders Power Dam regulates the water level of the lake. Geography Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7,340 sq mi, 18,960 km2), although it exceeds Lake Eri ...

Niagara Escarpment
The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that runs predominantly east–west from New York through Ontario, Michigan, Wisconsin, and into Illinois. The escarpment is most famous as the cliff over which the Niagara River plunges at Niagara Falls, for which it is named. The escarpment is a UNESCO World Biosphere Reserve. The reserve has the oldest forest ecosystem and trees in eastern North America. The escarpment is not a fault line but the result of unequal erosion. It is composed of an outcrop belt of the Lockport Formation of Silurian age, and is similar to the Onondaga Formation, which runs in a parallel outcrop belt just to the south, through western New York and southern Ontario. The escarpment is the most prominent of several escarpments formed in the bedrock of the Great Lakes Basin. From its easternmost point near Watertown, New York, the escarpment shapes in part the individual basins and landforms of Lake Ontario, Lak ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
