Niger Vallis is a valley on Mars that appears to have been carved by water. It has been identified as an outflow channel. It merges with Dao Vallis which runs southwestward into Hellas Planitia from the volcanic Hadriacus Mons. Like Dao, it was formed around the Late Noachian and Early Hesperian Epochs. It is named after the Niger River in Africa. (en) La Niger Vallis è una struttura geologica della superficie di Marte. (it) Niger Vallis é um vale em Marte aparentemente cravado pela ação da água, que corre em direção a Hellas Planitia partindo da cadeia vulcânica de Hadriacus Mons. Como Dao, este vale se formou por volta do período Noachiano superior e Hesperiano inferior. Seu nome vem do Rio Niger na África. (pt) 尼日谷（Niger Vallis）是火星上一处有流水侵蝕特徵出現的峽谷，被認為是一条溢出河道。該峽谷自哈德里亞卡山起源，向西南方和道谷合流後向流入希臘平原。尼日谷和道谷一樣大約形成於諾亞紀晚期或赫斯珀利亞紀早期。該峽谷長度333公里，以非洲尼日河命名。 (zh) |
