13-694: It takes the name from Redknife River , a tributary of the Mackenzie River , and was first described in the banks of the Trout River, north of Trout Lake, Northwest Territories , at Table Rock Rapids by Belyea and McLaren in 1962. The Redknife Formation is divided into the Jean Marie Member (base) and an upper unnamed shale unit. The Jean Marie Member is composed of argillaceous, silty and dolomitic fossiliferous limestone . The carbonates are massive east of Fort Nelson and west of

26-566: A junction 3.5 km (2.2 mi) from the island that includes "downtown" Fort Simpson, was finally opened in 1994 and includes the N'dulee ferry and ice crossings. On November 8, 2013, the portion of the highway from the Alberta/Northwest Territories border to Enterprise was designated the Highway of Heroes. There are social and economic studies being done on the extension of the highway north from Wrigley to join

Mackenzie Highway The Mackenzie Highway is a Canadian highway in northern Alberta and the Northwest Territories . It begins as Alberta Highway 2 at Mile Zero in Grimshaw, Alberta . After the first 4.0 km (2.5 mi), it becomes Alberta Highway 35 for the balance of its length through Alberta and then becomes Northwest Territories Highway 1 . The Mackenzie Highway

It is a major tributary of the Mackenzie River . The Redknife Formation , a stratigraphical unit of the Western Canadian Sedimentary Basin was named for the river. The Redknife river originates in

65-575: Is designated as part of Canada's National Highway System , holding core route status from its terminus at Grimshaw to its intersection with the Yellowknife Highway , and northern/remote route status for the remainder of the route to its northern terminus at Wrigley . Originally begun in 1938, prior to World War II , the project was abandoned at the outbreak of war. It resumed in the late 1940s and completed to Hay River, Northwest Territories , in 1948/1949, but some sections, particularly in

78-662: The Alberta border. The upper Redknife consists of calcareous shales with silty limestone and siltstone interbeds. To the south and east, the shales grade into limestone and siltstone, and it becomes dolomitic in the Peace River arch. The Redknife formation contains common coral and brachiopod fossils. Gas is produced from the Jean Marie Member in the Greater Sierra filed east of Fort Nelson, British Columbia . The Redknife Formation occurs in outcrops in

91-548: The Dempster Highway ; the territorial government has completed 34 bridges across all but six of the widest river crossings that serve the ice road and await the all-weather route. In June 2018, an announcement of $ 140 million funding would result in a bridge over Great Bear River and extend the Mackenzie Highway's all-weather road north by 15 km to Mount Gaudet. Just east of Fort Simpson's airport,

104-615: The Redknife Hills , at an elevation of 765 meters (2,510 ft). It flows east down the slopes of the hill, then turns north, draws water from a lake system, then turns north-east. It is crossed by the Mackenzie Highway , then turns north and flows into the Mackenzie River at an elevation of 145 meters (476 ft), 100 kilometers (62 mi) downstream from Fort Providence and 75 kilometers (47 mi) upstream from Jean Marie River .

117-830: The shale facies of the Fort Simpson Formation . East of the Peace River Arch it turns into the carbonates of the Kakisa Formation . The Redknife Formation is conformly overlain by the Kakisa Formation and overlies the Tathlina Formation in northern Alberta and the Fort Simpson Formation in British Columbia and Northwest Territories . The Fort Simpson Formation replaces the Redknife Formation to

130-506: The Yellowknife Highway. The 39 km (24 mi) stretch from Enterprise to Hay River is Northwest Territories Highway 2 . Around 1970, the highway was extended west from what is now the southern terminus of Highway 3 to reach Fort Simpson , and in 1971, when the section to Fort Simpson was opened to traffic, work began to prepare a road grade from there to Wrigley , but the work was abandoned. The roadway, which starts at

143-399: The southern Northwest Territories and in the sub-surface in north-eastern British Columbia , also reaching into north-western Alberta . The maximum thickness of the upper shales is 79 feet (20 m), and the lower carbonates are up to 15 feet (0 m). The Jean Marie Member is found in outcrops south of the Mackenzie River between Kakisa and Blackstone River. It grades westwards into

156-561: The vicinity of Steen River , remained difficult. In 1960, it was extended from Enterprise , approximately 39 km (24 mi) south of Hay River, to the northwest, then north past Fort Providence to Behchokǫ̀ (at the time, known as Rae-Edzo) and southeast to the City of Yellowknife , which became the capital of the Northwest Territories in 1967. Much of the extension is now known as Northwest Territories Highway 3 , or

169-676: The west. The Redknife Formation can be correlated with the Nisku Formation and upper part of the Ireton Formation in central Alberta . The Jean Marie Member is designated as the lower part of the Redknife Formation where it is represented by massive limestone or silty carbonates . The Jean Marie Member was deposited during the Frasnian age. It is named for the Jean Marie River . This article about
