烏斯缽-拉冬-摩拉瓦谷

維基百科,自由的百科全書

烏斯缽-拉冬-摩拉瓦 (Uzboi-Landon-Morava) 溢道系統是一長串的河床和窪地,可能曾攜帶着水流穿過了火星大部分的地區。它啟源於流入阿耳古瑞區阿耳古瑞盆地的河道。積蓄在阿耳古瑞盆地中的大水,據說隨後漫溢而出向北奔流,一路穿過烏斯缽谷,進入拉冬盆地,再穿越摩拉瓦谷,最後抵達珍珠灣盆底[1][2][3]。其中部分水流可能沖刷蝕刻了阿瑞斯谷 [4][5][6][7][8] 。總之,該流域的總溢流面積可能約為 11 X 106公里2或約火星9% 的表面[9][2]

下面的圖片顯示了曾經被水注滿的阿耳古瑞盆地。此外,更廣闊的視圖顯示了水流穿越的距離,從阿耳古瑞盆地以南一直到珍珠高地
