It lies in low-relief terrain of the Canadian Shield. The climate is sub-arctic. The land is mostly covered by conifer forests, with some areas of muskeg and rocky outcrops. LocationMcArthur Lake is at {{coord|55.2501|-102.4004}}, at an elevation of {{convert|328|m}}.{{sfn|McArthur Lake – Mapcarta}}{{efn|There is another McArthur Lake in Saskatchewan at {{coord|52|34|0|N|104|22|0|W}}.{{sfn|Gazetteer of Canada: Saskatchewan|p=51}} }} The lake contains Charbonneau Island.{{sfn|Pyke|1961|p=28}} It is northwest of Flin Flon, Manitoba, and east of Pelican Narrows, Saskatchewan.{{sfn|Pyke|1961|p=5}} McArthur Lake drains northward into the Churchill River via the Nemei River.{{sfn|Pyke|1961|p=5}} The lake is named in honour of Duncan Archibald McArthur, a private soldier who died on 28 August 1944 during the Allied invasion of Normandy.{{sfn|Duncan Archibald McArthur}} TerrainThe Attitti Lake region, which includes McArthur Lake, is typical of the flat-surfaced part of the Canadian Shield, with low hills that rarely rise as much as {{convert|100|to|150|ft}} above the lakes.{{sfn|Pyke|1961|p=5}} The terrain consists of roughly parallel sinuous ridges of outcrop separated by muskeg, drift and lakes.{{sfn|Pyke|1961|p=5}} Geologically the area is in the Precambrian Kisseynew complex, underlain by an assemblage of metamorphosed sedimentary rocks that has been intricately folded, with intrusions of sill-like granitic bodies.{{sfn|Pyke|1961|p=8}} In its northern section the McArthur Lake fault zone is parallel to the east shore of McArthur Lake, forming a steep scarp {{convert|75|to|100|ft}} high. The fault zone runs south to a location about {{convert|1|mi}} north of Galbraith Lake.{{sfn|Pyke|1961|p=20}} The Galbraith Lake folds is an open asymmetric overturned syncline with an axial plane trending 25° NE, dipping very sharply to the east, that extends south from the south end of McArthur Lake to the south of Galbraith Lake.{{sfn|Pyke|1961|p=18}} There are a number of northerly plunging folds between McArthur and Kakinagimak lakes with axial planes 20° NE, dipping sharply to the east.{{sfn|Pyke|1961|p=19}} EnvironmentThe lake is in the subarctic climate zone.{{sfn|Peel|Finlayson |McMahon|2007}} The annual average temperature is {{convert|-2|°C}}. The warmest month is July, when the average temperature is {{convert|16|°C}} and the coldest is January, with {{convert|-29|°C}}.{{sfn|Dataset Index – NASA}} The lake is surrounded by coniferous forest.{{sfn|Land Cover Classification – NASA}} The trees are mainly black spruce (Picea mariana), jack pine (Pinus banksiana), poplar (populus) and scattered balsam (populus balsamifera). Trees average more than {{convert|20|ft}} in height.{{sfn|Pyke|1961|p=5}} There are small patches of moss-covered muskeg that support laurel (kalmia microphylla), labrador tea, and scattered larch and black spruce.{{sfn|Pyke|1961|p=6}} Animals hunted for meat or fur include moose, woodland cariboo, black bear, beaver, otter and muskrat. Spruce partridge are common.{{sfn|Pyke|1961|p=6}} MineralsDark gray to black garnet-hornblende gneiss is exposed in an area from north of Bentz Bay to just south of McArthur Lake.{{sfn|Pyke|1961|p=9}} Small areas of hornblende and/or biotite migmatite are found near the lake. The light to dark gray outcrops are usually rounded and weathered.{{sfn|Pyke|1961|p=14}} Dykes, lenses, and veins of pegmatite are abundant in the meta-sedimentary rocks and granitic bodies between the north of Attitti Lake and McArthur Lake.{{sfn|Pyke|1961|p=17}} The northeast shore of Charbonneau Island has chalcopyrite and pyrite associated with stringers of pink pegmatite in biotite-hornblende migmatite. In 1958 the Hudson Bay Exploration and Development Company staked claims to this area based on a aerial electromagnetic and magnetometer survey. The company undertook a geophysical survey and some diamond drilling, then allowed the claims to lapse.{{sfn|Pyke|1961|p=21}} Notes{{notes}}CitationsSources{{refbegin}}
