Richmond Gulf ((フランス語:Lac Guillaume-Delisle); (イヌクティトゥット語:''Tasiujaq'' (which resembles a lake))) is a large triangular-shaped inland bay located on east side of Hudson Bay just above 56th parallel north in Quebec, Canada. In 2008, regional councilors asked the Commission de toponymie du Québec to rename Richmond Gulf officially as Lac Tasiujaq. A vast area surrounding the gulf, Clearwater Lakes (''Lacs à l'Eau-Claire''), and Iberville Lake (''Lac D'Iberville'') was included in the Tursujuq National Park, officially established on July 18, 2013.〔Ministère du Développement durable, de l’Environnement et des Parcs, ''Provisional Master Plan Parc national des Lacs-Guillaume-Delisle-et-à-l'Eau-Claire'', Quebec, 2008, ISBN 978-2-550-52710-7 ((Online version ))〕 ==Geography== The topography of the Richmond Gulf is the consequence of two geological faults running parallel to the coast. The resulting dislocation has given rise to the cliffs that dominate the western shore of the Gulf. The western shore is guarded by the steep ramparts of sedimentary rock that rise abruptly out of the brackish waters. This unusual coastal relief of asymmetrical hills are the Hudsonian Cuestas and the highest system of cuestas found in Quebec.〔 There is only one narrow breach in these fortifications at the extreme southwest end, called "''Le Goulet''" (French meaning "narrows" or "bottleneck"), which is a cataclinal valley long, wide and fringed by cliffs high.〔 A large volume of water surges through it with the rise and fall of the tides, creating water level differences of about .〔 Consequently, this passage does not freeze in the winter. The eastern shore rises more gradually and is largely Canadian Shield rock, overlain in many places by basalt. Several large rivers enter Richmond Gulf in boisterous rapids or sheer falls (e.g. Clearwater River). Point Pamiallualuk is a narrow spur of rock that juts out some 2 km into Hudson Bay, just north of Le Goulet. Here, the north-flowing tidal current of Hudson Bay collides with weaker counter-current to produce a lot of agitation, which is further enhanced by the strong wind.〔 On the south shore, there are the remnants of an abandoned Hudson's Bay Company trading post, called Fort Richmond, which operated from 1750 to 1759 and from 1921 to 1927.〔〔(Hudson's Bay Company Archives )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Richmond Gulf」の詳細全文を読む スポンサード リンク
