The Fortescue River is an ephemeral river in the Pilbara region of Western Australia. It is the third longest river in the state. The river rises near Deadman Hill in the Ophthalmia Range about 30 km south of Newman. The river flows in a northerly direction parallel with the Great Northern Highway until it crosses the highway just south of the Marble Bar turn-off. The river then runs north-west then west crossing the Great Northern Highway again, north of the Auski Roadhouse. Approximately north of Newman, the river flows through the Fortescue Marsh, an important wetland. The river continues to head west crossing Highway 1 at the Fortescue Roadhouse () and discharges into the Indian Ocean at Mardie Station about 40 km south-west of Dampier The river was named in 1861 during an expedition by the explorer and surveyor Francis Thomas Gregory, after Chichester Fortescue, Parliamentary Under-Secretary of State for the Colonies. The traditional owners of the area that the river flows through are the ''Indjibandi'' peoples.〔(【引用サイトリンク】title= AusAnthrop Australian Aboriginal tribal database )〕 == Tributaries == The river is known to have 24 tributaries that include: Western Creek, Warrawanda Creek, Shovelanna Creek, Kalgan Creek, Fortescue River South, Cowcumba Creek, Macklin Creek and Tanga Tanga Creek. During Cyclone Joan in 1975 many of these tributaries also flooded. Weeli Wolli Creek and Weelumurra Creek both overflowed and caused floods and washaways on the Hamersley Iron and Mount Newman railway lines.〔(【引用サイトリンク】title=Tropical Cyclone Joan )〕 The river flows through a number of permanent water pools on the latter part of its journey including Tarda Pool, Mungowarra Pool, Crossing Pool and Deep Reach Pool. 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「Fortescue River」の詳細全文を読む スポンサード リンク
