75-806: Completed in 1900, the Low Level Bridge was the first bridge across the North Saskatchewan River. It was designed to carry a railway, and a railway track was added in 1902 to accommodate the Edmonton, Yukon and Pacific Railway (amalgamated with the Canadian Northern Railway in 1905). It was originally known simply as the Edmonton Bridge or the Inter-Urban Bridge (connecting the towns of Strathcona and Edmonton) until it became known as

150-736: A charter to build westward to the mouth of the Skeena River was alarmed, but in no hurry, because it believed the GTPR would choose one of the more northerly passes to cross the Canadian Rockies , leaving the Yellowhead Pass for the CNoR. Despite promptings, the GTP was unwilling to collaborate with the CNoR in any joint construction. In 1905, CNoR reached Edmonton , just as part of the old NWT had changed into

225-441: A condition for further funding, the government became the majority shareholder. On September 6, 1918, the directors, Mackenzie and Mann, resigned, replaced by a government-appointed board. Subsequently, CNoR executive David Blyth Hanna and his team managed not only CNoR operations but also the federally owned Canadian Government Railways (CGR). On December 20, 1918, a Privy Council order directed CNoR and CGR to be managed under

300-550: A specific bridge in Canada is a stub . You can help Misplaced Pages by expanding it . Canadian Northern Railway The Canadian Northern Railway ( CNoR ) was a historic Canadian transcontinental railway . At its 1923 merger into the Canadian National Railway ( reporting mark CN ), the CNoR owned a main line between Quebec City and Vancouver via Ottawa , Winnipeg , and Edmonton . The network had its start in

375-463: A sunken body will bloat it with gas, causing it to float to the surface after a few days. But Lake Superior's water is cold enough year-round to inhibit bacterial growth , and bodies tend to sink and never resurface. Joe MacInnis reported that in July 1994, explorer Frederick Shannon's Expedition 94 to the wreck of Edmund Fitzgerald discovered a man's body near the port side of her pilothouse, not far from

450-453: A trans-Pacific service were mothballed. In 1914, to develop a resort on Grand Beach , CNoR bought a 150-acre (0.61 km ) homestead north of Winnipeg on the shores of Lake Winnipeg, By 1914, with the company's financial predicament threatening the solvency of its major financier, the Bank of Commerce , the CNoR appealed for government help. The last spike of the CNoR transcontinental railway

525-475: A very small ratio (1.55) of catchment area to surface area, which indicates minimal terrestrial influence. American limnologist J. Val Klump was the first person to reach the lowest depth of Lake Superior on July 30, 1985, as part of a scientific expedition, which at 122 fathoms 1 foot (733 ft or 223 m) below sea level is the second-lowest spot in the continental interior of the United States and

600-686: Is Isle Royale in Michigan. Isle Royale contains several lakes, some of which also contain islands. Other well-known islands include Madeline Island in Wisconsin, Michipicoten Island in Ontario, and Grand Island (the location of the Grand Island National Recreation Area ) in Michigan. The larger cities on Lake Superior include the twin ports of Duluth, Minnesota , and Superior, Wisconsin ; Thunder Bay , Ontario; Marquette, Michigan ; and

675-408: Is 0.33 feet (0.10 m) below the datum. In the winter of 1926 Lake Superior reached its lowest recorded level at 1.58 feet (0.48 m) below the datum. Additionally, the entire first half of the year (January to June) included record low months. The low water was a continuation of the dropping lake levels from the previous year, 1925, which set low-water records for October through December. During

750-423: Is 4,229 feet (1,289 m) above sea level.) While the temperature of the surface of Lake Superior varies seasonally, the temperature below 110 fathoms (660 ft; 200 m) is an almost constant 39 °F (4 °C). This variation in temperature makes the lake seasonally stratified . Twice per year, however, the water column reaches a uniform temperature of 39 °F (4 °C) from top to bottom, and

825-493: Is 80.5 fathoms (483 ft; 147 m) with a maximum depth of 222.17 fathoms (1,333 ft; 406 m). Lake Superior contains 2,900 cubic miles (12,100 km ) of water. There is enough water in Lake Superior to cover the entire land mass of North and South America to a depth of 30 centimetres (12 in). The shoreline of the lake stretches 2,726 miles (4,387 km) (including islands). The lake boasts

900-528: Is a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River. Lake Superior's size reduces the severity of the seasons of its humid continental climate (more typically seen in locations like Nova Scotia ). The water surface's slow reaction to temperature changes, seasonally ranging between 32 and 55 °F (0–13 °C) around 1970, helps to moderate surrounding air temperatures in

975-449: Is an unusual record of environmental nitrogen buildup. It may relate to anthropogenic alternations to the regional nitrogen cycle , but researchers are still unsure of the causes of this change to the lake's ecology. As for other Great Lakes fish, populations have also been affected by the accidental or intentional introduction of foreign species such as the sea lamprey and Eurasian ruffe . Accidental introductions have occurred in part by

1050-782: The Canada–United States border with the Canadian province of Ontario to the north and east and the U.S. states of Minnesota to the west and Michigan and Wisconsin to the south. It drains into Lake Huron via St. Marys River , then through the lower Great Lakes to the St. Lawrence River and ultimately the Atlantic Ocean. The Ojibwe name for the lake is gichi-gami (in syllabics : ᑭᒋᑲᒥ , pronounced gitchi-gami or kitchi-gami in different dialects), meaning "great sea". Henry Wadsworth Longfellow wrote this name as " Gitche Gumee " in

1125-542: The Duluth, Winnipeg and Pacific Railway , forms part of a key CN connection between Chicago and Winnipeg . Lake Superior Lake Superior is the largest freshwater lake in the world by surface area and the third-largest freshwater lake by volume , holding 10% of the world's surface fresh water. Located in central North America, it is the northernmost and westernmost of the Great Lakes of North America , straddling

1200-671: The Hudson Bay watershed, are regulated by the International Lake Superior Board of Control , which was established in 1914 by the International Joint Commission . Lake Superior's water level was at a new record low in September 2007, slightly less than the previous record low in 1926. Water levels recovered within a few days. Historic high water The lake's water level fluctuates from month to month, with

1275-471: The Mount Royal Tunnel project. CNoR was heavily indebted to banks and governments, and its profitable branchlines in the prairie provinces — "Canada's breadbasket" — would not generate enough revenue to cover construction costs in other areas. Unable to meet its debts, the company became desperate for financial aid. In 1917, the federal government effectively took control of the company. As

1350-732: The Pic River , the White River , the Michipicoten River , the Bois Brule River and the Kaministiquia River . The lake's outlet at St. Marys River has a relatively steep gradient with rapids. The Soo Locks enable ships to bypass the rapids and to overcome the 25-foot (8 m) height difference between Lakes Superior and Huron. The lake's average surface elevation is 600 feet (183 m) above sea level . Until approximately 1887,

1425-739: The Whitefish Point Underwater Preserve . Storms that claimed multiple ships include the Mataafa Storm in November 1905 and the Great Lakes Storm of 1913 . Wreckage of SS  Cyprus —a 420-foot (130 m) ore carrier that sank on October 11, 1907, during a Lake Superior storm in 77 fathoms (460 ft or 140 m) of water—was located in August 2007. Built in Lorain, Ohio , Cyprus

1500-495: The lake effect snow belts along the shores of the lake, especially in the Upper Peninsula of Michigan . Two recent consecutive winters (2013–2014 and 2014–2015) brought high ice coverage to the Great Lakes, and on March 6, 2014, overall ice coverage peaked at 92.5%, the second-highest in recorded history. Lake Superior's ice coverage further beat 2014's record in 2019, reaching 95% coverage. The largest island in Lake Superior

1575-476: The 1890s and 1900s had been relatively frugal, largely by acquiring bankrupt companies or finishing failed construction projects. By the 1910s, significant expenses were accumulating. The CNoR started construction west of Edmonton in 1910, fully two years later than GTPR. The construction through the Rockies, which was expensive, largely paralleled the GTPR line of 1911, creating about 100 miles of duplication. However,

1650-558: The 1890s, they reached Swan River , and continued building north between the Porcupine Hills to the west and Lake Winnipegosis to the east. In 1900, Mackenzie and Mann directed this northern line west into the Northwest Territories (later Saskatchewan ), where it eventually terminated at E.R. Wood (later Erwood ). This northwestern line mainly carried lumber and was extended to Melfort between 1903 and 1905. In 1907,

1725-506: The CNoR, the line extended south of Lake of the Woods into northern Minnesota before heading northeast through Rainy River District to the head of navigation on the Great Lakes . The Winnipeg-Port Arthur line was completed on December 30, 1901, with the last spike being driven just east of Atikokan station by Ontario's Commissioner of Crown Lands , Elihu Davis . Meanwhile, Mackenzie and Mann expanded their prairie branch line operations to feed

1800-563: The Canadian Parliament pressured Mackenzie and Mann to continue building more rail towards Hudson Bay. In that year, they created a junction on the Erwood to Melfort line near the mouth of the Etoimami river, where Fort Red Deer River existed, and a line was extended north to The Pas . By 1910, the settlement at this junction was renamed Hudson Bay Junction , and the line was completed between

1875-513: The Hudson's Bay Company name. Many towns around the lake are current or former mining areas, or engaged in processing or shipping. Today, tourism is another significant industry: the sparsely populated Lake Superior country, with its rugged shorelines and wilderness, attracts vacationers and adventurers. Lake Superior has been an important link in the Great Lakes Waterway , providing a route for

1950-583: The Low Level Bridge some time after the completion of the High Level Bridge . The bridge was in danger of overturn during the North Saskatchewan River flood of 1915 . The floodwater peaked just below the level of the bridge deck itself, with flood-carried debris piling along its length. A train was parked on the bridge to help hold it in place. The peak level was estimated to be about 13 metres (42 ft) above low water level. Streetcars used

2025-593: The Midcontinent Rift, and there are several amethyst mines in the Thunder Bay area. Lava erupted from the rift and formed the black basalt rock of Michipicoten Island, Black Bay Peninsula, and St. Ignace Island . In the most recent geological history, during the Wisconsin glaciation 10,000 years ago, ice covered the region at a thickness of 1.25 miles (2 km). The land contours familiar today were carved by

2100-548: The Ojibwe name as Otchipwe-kitchi-gami (a transliteration of Ojibwe Gichigami ). In the 17th century, the first French explorers approached the great inland sea by way of the Ottawa River and Lake Huron; they referred to their discovery as le lac supérieur (the upper lake, i.e., above Lake Huron). Some 17th-century Jesuit missionaries referred to it as Lac Tracy (for Alexandre de Prouville de Tracy ). After taking control of

2175-656: The Skeena, the CNoR accepted BC government subsidies to switch to the Vancouver area. When the GTPR selected the Yellowhead route, CNoR protests created some delay but could not overturn he decision. In 1911, CNoR workers started on a townsite named Port Mann on the Fraser River. This townsite would accommodate new car shops, and from there, rail-lines would extend to Vancouver and the Fraser River delta. CNoR's initial expansion in

2250-563: The Stony Plain line meant frequent crossings over the Grand Trunk Pacific line which had been laid in the meantime. Instead CNoR decided to leave Edmonton through St. Albert. (A bump on 124th Street near Stony Plain Road is remnant of the constructed but abandoned road-bed.) CNoR's terminus on the coast changed over time. Rather than competing with the GTPR in having a terminal at the mouth of

2325-472: The Toronto – Parry Sound line to Ottawa and on to Montreal . In 1910 a direct Toronto–Montreal line was built. In 1911, federal funding enabled construction of the line Montreal – Ottawa – Capreol – Port Arthur. In 1912, with GTR and CPR holding the ideal southern routes around Mount Royal to downtown Montreal, CNoR started building a double-tracked mainline north by excavating the Mount Royal Tunnel . In 1910

2400-599: The acquisition of branchlines in southwestern Nova Scotia (the Halifax and Southwestern Railway ) and western Cape Breton Island (the Inverness and Richmond Railway ). Other acquisitions were in southern Ontario and a connecting line was built from Toronto to Parry Sound . In 1908, a line, which under later CN ownership was known as the Alderdale Subdivision , was built east from a connection at Capreol, Ontario , on

2475-478: The advance and retreat of the ice sheet . The retreat left gravel, sand, clay and boulder deposits. Glacial meltwaters gathered in the Superior basin creating Lake Minong , a precursor to Lake Superior. Without the immense weight of the ice, the land rebounded , and a drainage outlet formed at Sault Ste. Marie, becoming today's St. Mary's River. The first people came to the Lake Superior region 10,000 years ago after

2550-609: The arrival of Europeans, the Anishinaabe made themselves middle-men between the French fur traders and other Native peoples. They soon became the dominant Native American nation in the region: they forced out the Sioux and Fox and won a victory against the Iroquois west of Sault Ste. Marie in 1662. By the mid-18th century, the Ojibwe occupied all of Lake Superior's shores. In the 18th century, as

2625-586: The booming fur trade supplied Europe with beaver hats , the Hudson's Bay Company had a virtual monopoly in the region until 1783, when the rival North West Company was formed. The North West Company built forts on Lake Superior at Grand Portage , Fort William , Nipigon, the Pic River, the Michipicoten River, and Sault Ste. Marie. But by 1821, with competition harming the profits of both, the companies merged under

2700-465: The bridge (on a gauntlet track ) from 1908 to 1939. Trolley buses of the Edmonton trolley bus system used the bridge from the removal of the streetcar track in 1939 until 1965. In 1948 a twin span of the same design was added upstream of the original span. The new span was originally used for vehicle traffic in both directions, with the original span being reserved for railway use. When the railway track

2775-689: The company entered the trans-Atlantic liner business with the founding of the Canadian Northern Steamship Company. The subsidiary acquired two liners from the Egyptian Mail Steamship Company and operated them under its Royal Line brand. The pair of ships were renamed upon purchase— Cairo became Royal Edward and Heliopolis became Royal George —and refitted for travel on the North Atlantic. In Royal Line service, Royal Edward sailed from Avonmouth to Montreal in

2850-576: The connection to Port Arthur. From a series of disconnected railways and charters, the network became 1,200 miles of profitable and continuous track that covered most of the prairies by 1902. After receiving grants from the Province of Manitoba and the Dominion of Canada in the 1890s, Mackenzie and Mann began building lines further north in Manitoba, with the intention of eventually reaching Hudson Bay . Throughout

2925-608: The direct ancestors of the Ojibwe and Cree . The people of the Laurel complex (c. 500 BC to AD 500) developed seine net fishing, evidence being found at rivers around Superior such as the Pic and Michipicoten. The people of the Terminal Woodland period were evident in the area from AD 900 to 1650. They were Algonquian peoples who hunted, fished and gathered berries. They used snowshoes , birch bark canoes and conical or domed lodges. At

3000-526: The highest lake levels in October and November. The normal high-water mark is 1.17 feet (0.36 m) above the datum (601.1 ft or 183.2 m). In the summer of 1985, Lake Superior reached its highest recorded level at 2.33 feet (0.71 m) above the datum. 2019 and 2020 set new high-water records in nearly every month. Historic low water The lake's lowest levels occur in March and April. The normal low-water mark

3075-486: The independent branchlines that were being constructed in Manitoba in the 1880s and 1890s as a response to the monopoly exercised by Canadian Pacific Railway (CPR). Many such lines were built with the sponsorship of the provincial government, which sought to subsidize local competition to the federally subsidized CPR; however, significant competition was also provided by the encroaching Northern Pacific Railway (NPR) from

3150-425: The junction and The Pas. The long section of rail between The Pas and Churchill was never completed by CNoR. However, after CNoR was acquired by CN , the line was completed in 1929. (see Hudson Bay Railway ) Once elected in 1896, Prime Minister Wilfrid Laurier was eager for a second transcontinental. However, an expansion of the non- CPR railways west of Alberta would be a mammoth questionable gamble for

3225-621: The lake appeared to have increased by about 4.5 °F (2.5 °C) between 1979 and 2007, compared with an approximately 2.7 °F (1.5 °C) increase in the surrounding average air temperature. The increase in the lake's surface temperature may be related to the decreasing ice cover. Less winter ice cover allows more solar radiation to penetrate and warm the water. If trends continue, Lake Superior, which freezes over completely once every 20 years, could routinely be ice-free by 2040 although more current data through 2021 does not support this trend. Warmer temperatures could lead to more snow in

3300-527: The lake waters thoroughly mix. This feature makes the lake dimictic . Because of its volume, Lake Superior has a retention time of 191 years. Annual storms on Lake Superior regularly feature wave heights of over 20 feet (6 m). Waves well over 30 feet (9 m) have been recorded. Lake Superior is fed by more than 200 rivers, including the Nipigon River , the St. Louis River , the Pigeon River ,

3375-522: The lake. With 78 crewmembers dead, their sinking marked the largest loss of life on Lake Superior to date. SS  Edmund Fitzgerald is the last ship that sank in Lake Superior, 15 nautical miles (28 km; 17 mi) from Whitefish Point in a storm on November 10, 1975. The wreck was immortalized by Gordon Lightfoot in his ballad "The Wreck of the Edmund Fitzgerald " . All 29 crew members died, and no bodies were recovered. Edmund Fitzgerald

3450-629: The largest costs were from building on "the wrong side" of the Thompson and Fraser rivers in the Coast Mountains of British Columbia. CPR already had trackage on the desirable banks, forcing the CNoR to blast tunnels and ledges out of these canyons. The most infamous construction folly on the CNoR in British Columbia happened in 1913, when blasting for a passage for the railway at Hells Gate triggered an enormous landslide which partially blocked

3525-446: The most frequently mined. Notable production includes gold from the Hemlo mine near Marathon , copper from the Keweenaw Peninsula and the Mamainse Point Formation , iron from the Gogebic Range , silver at Silver Islet , and uranium at Theano Point. The mountains steadily eroded, depositing layers of sediments that compacted and became limestone , dolomite , taconite and the shale at Kakabeka Falls . The continental crust

3600-407: The mouth of the Michipicoten River, nine layers of encampments have been discovered. Most of the Pukaskwa Pits were likely made during this time. The Anishinaabe people (an ethnic grouping including the Ojibwe/Chippewa ) have inhabited the Lake Superior region for over five hundred years and were preceded by the Dakota , Meskwaki (Fox) , Menominee , Nipigon, Noquet and Gros Ventres . After

3675-531: The name Canadian National Railway (CNR) as a means to simplify funding and operations, but CNoR and CGR would not formally merge and cease corporate existence until January 20, 1923, the date Parliament passed the final act to incorporate CNR. Significant portions of the old CNoR system survive under CN (as the CNR has been known since 1960); for example: The majority of CN's former CNoR branchline network across Canada has either been abandoned or sold to shortline operators. An important U.S. subsidiary of CNoR,

3750-402: The narrow swift-flowing Fraser River. The resulting damage to Pacific salmon runs took decades to reverse by the governmental construction of fishways . Mackenzie and Mann began their first significant expansion outside of the prairies with the purchase of Great Lakes steamships, the Quebec and Lake St-John Railway  [ fr ] (1906) into northern Quebec 's Saguenay region and

3825-468: The natural hydraulic conveyance through the St. Marys River rapids determined the outflow from Lake Superior. By 1921, development in support of transportation and hydroelectric power resulted in gates, locks, power canals and other control structures completely spanning St. Marys rapids. The regulating structure is known as the Compensating Works and is operated according to a regulation plan known as Plan 1977-A. Water levels, including diversions of water from

3900-453: The nine-month period of October 1925 to June 1926, water levels ranged from 1.58 feet (0.48 m) to 0.33 feet (0.10 m) below Chart Datum. In the summer of 2007 monthly historic lows were set; August at 0.66 feet (0.20 m), and September at 0.58 feet (0.18 m). According to a study by professors at the University of Minnesota Duluth , Lake Superior may have warmed faster than its surrounding area. Summer surface temperatures in

3975-976: The open door, "fully clothed, wearing an orange life jacket, and lying face down in the sediment". In February 2024 it was announced that wreckage from the Arlington was discovered from a sinking in 1940. More than 80 species of fish have been found in Lake Superior. Species native to the lake include banded killifish , bloater , brook trout , burbot , cisco , lake sturgeon , lake trout , lake whitefish , longnose sucker , muskellunge , northern pike , pumpkinseed , rock bass , round whitefish , smallmouth bass , walleye , white sucker and yellow perch . In addition, many fish species have been either intentionally or accidentally introduced to Lake Superior: Atlantic salmon , brown trout , carp , chinook salmon , coho salmon , freshwater drum , pink salmon , rainbow smelt , rainbow trout , round goby , ruffe , sea lamprey and white perch . Lake Superior has fewer dissolved nutrients relative to its water volume than

4050-431: The operators. Adding an equally costly route to supplement the existing uneconomical CP track through Ontario seemed more ludicrous. At the time, the CNoR planned to advance no further west than Edmonton. In 1902, the GTR held talks with Laurier and agreed to build a transcontinental under the auspices of the GTPR for the western portion, with the eastern portion built by the government-owned NTR . The CNoR, which had

4125-514: The other Great Lakes and so is less productive in terms of fish populations and is an oligotrophic lake . This is a result of the underdeveloped soils found in its relatively small watershed. It is also a reflection of relatively small human population and small amount of agriculture in its watershed. However, nitrate concentrations in the lake have been continuously rising for more than a century. They are still much lower than levels considered dangerous to human health; but this steady, long-term rise

4200-500: The other Great Lakes began sailing in 1816. Ice closes the lake shipping from mid-January to late March. Exact dates for the shipping season vary each year, depending on weather conditions that form and break the ice. The southern shore of Lake Superior between Grand Marais, Michigan , and Whitefish Point is known as the " Graveyard of the Great Lakes "; more ships have been lost around the Whitefish Point area than any other part of Lake Superior. These shipwrecks are now protected by

After a pause, the CNoR began construction west from Edmonton, and by summer 1907 had gone as far as Stony Plain. A stock market crash that year ceased construction. When construction was resumed in 1910, it was found that extending

The Shield Archaic peoples arrived around 5000 BC; evidence of this culture can be found at the eastern and western ends of the Canadian shore. They used bows and arrows, paddled dugout canoes, fished, hunted, mined copper for tools and weapons, and established trading networks. They are believed to be

The partners expanded their enterprise, in 1897, by building further north into Manitoba's Interlake district as well as east and west of Winnipeg . They also began building and buying lines south to connect with the U.S. border at Pembina, North Dakota , and east to Ontario . The Canadian Northern Railway

The hills and mountains that border the lake hold moisture and fog, particularly in the fall. The rocks of Lake Superior's northern shore date back to the early history of the earth. During the Precambrian (between 4.5 billion and 540 million years ago) magma forcing its way to

4800-456: The summer months and to Halifax in the winter months. At the outbreak of World War I , Royal Edward and Royal George were both requisitioned for use as troopships. On August 13, 1915, the German submarine UB-14 sank Royal Edward , which was transporting troops from Avonmouth to Gallipoli . Royal George was sold to Cunard in 1916, became an emigrant ship in Cherbourg by 1920 and scrapped in 1922 in Wilhelmshaven . Plans for

The Caspian Sea , while larger than Lake Superior in both surface area and volume, is brackish . Lake Superior has a surface area of 31,700 square miles (82,103 km ), which is approximately the size of South Carolina or Austria . It has a maximum length of 350 statute miles (560  km ; 300  nmi ) and maximum breadth of 160 statute miles (257 km; 139 nmi). Its average depth

5250-406: Was battered so intensely by Lake Superior that the 729-foot (222 m) ship split in half; her two pieces lie approximately 170 feet (52 m) apart at a depth of 88 fathoms (530 ft or 160 m). Lightfoot sings that "Superior, they said, never gives up her dead". This is because of the unusually cold water, under 36 °F (2 °C) on average around 1970. Normally, bacteria decaying

5475-531: Was later riven , creating one of the deepest rifts in the world. The lake lies in this long-extinct Mesoproterozoic rift valley , the Midcontinent Rift . Magma was injected between layers of sedimentary rock , forming diabase sills . This hard diabase protects the layers of sedimentary rock below, forming the flat-topped mesas in the Thunder Bay area. Amethyst formed in some of the cavities created by

5550-486: Was launched August 17, 1907, and was lost on her second voyage hauling iron ore from Superior, Wisconsin, to Buffalo, New York , with the sole survivor among her 23 crew being Charles G. Pitz. In 1918 the last warships to sink in the Great Lakes, French minesweepers Inkerman and Cerisoles , vanished in a Lake Superior storm, perhaps upon striking the uncharted danger of the Superior Shoal in an otherwise deep part of
