The Rahway Valles are a set of channels in a valley in the Elysium quadrangle of Mars, located at 9.4° North and 186.2° West. They are 500 kilometres (310 mi) long and were named after an American river in New Jersey.[1] The region was created by 'a'ā and pāhoehoe lava flows from the nearby Elysium volcanic province.[2]
