Location

Attitti Lake is at 55.1334°N 102.4671°W / 55.1334; -102.4671, at an elevation of 362 metres (1,188 ft).[1] The lake is northwest of Flin Flon, Manitoba and about 30 miles (48 km) east of Pelican Narrows, Saskatchewan. It is connected by a winter road with Kakinagimak Lake, Wildnest Lake and Hanson Lake highway (106), which runs 2 miles (3.2 km) south of Wildnest Lake. It can be reached by canoe from Pelican Narrows via Wunehikun Bay and Waskwei Lake, and is connected to most of the surrounding lakes by well-maintained portages.[2]

Terrain

The area is typical of the flat-surfaced part of the Canadian Shield, with low hills that rarely rise as much as 100 to 150 feet (30 to 46 m) above the lakes.[2] The terrain consists of roughly parallel sinuous ridges of outcrop separated by muskeg, drift and lakes.[2] The channel that connects Attitti Bay with Attitti Lake is underlain by a north-trending fault zone.[3] 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.[4] Metamorphism in the area appears to have peaked about 1807 million years ago. There is significant economic potential for volcanogenic massive sulfide and gold mineralization.[5]

The area has parts of three different drainage basins. Robbestad Lake, McArthur Lake and the northern part of Kakinagimak Lake drain northward into the Churchill River via the Nemei River. The southern part of Kakinagimak Lake, and Dezort Lake, Dougherty Lake, Wildnest Lake, and Pearson Lake drain south into the Wildnest-Sturgeon-Weir River System, then into the Saskatchewan River. The rest of the area drains into Attitti Lake, which drains eastward through Waskwei Lake, Wunehikun Bay, Mirond Lake and the Sturgeon-Weir River System into the Saskatchewan River System.[2]

Environment

The lake is in the subarctic climate zone.[6] The annual average temperature is −2 °C (28 °F). The warmest month is July, when the average temperature is 16 °C (61 °F) and the coldest is January, with −22 °C (−8 °F).[7] The lake is surrounded by coniferous forest.[8] The trees are mainly black spruce (Picea mariana), jack pine (Pinus banksiana), poplar (populus) and scattered balsam (populus balsamifera). Trees average more than 20 feet (6.1 m) in height.[2] There are small patches of moss-covered muskeg that support laurel (kalmia microphylla), labrador tea, and scattered larch and black spruce.[9]

Animals hunted for meat or fur include moose, woodland caribou, black bear, beaver, otter and muskrat. Spruce partridge are common.[9] There is a fly-in fishing lodge on the lake, which has a good population of lake trout, northern pike and walleye.[10]

    gollark: What they are saying is that values have types and not variables.
    gollark: Python type annotations don't actually do anything either.
    gollark: Metatables will let you override `type` nowadays I think.
    gollark: No, Python types *are themselves* objects which you can do object things too.
    gollark: In Python.
