Mangala Valles

Mangala Valles is a complex system of criss-crossing channels on Mars, located in the Tharsis region originating in the Amazonian epoch. "Mangala" comes from the word for Mars in Sanskrit. The channels were probably carved by water many thousands of years ago and lack tributaries. It appears that the water started coming out of the surface when a graben was formed.

There are many wind-sculpted ridges or yardangs covering many of the surfaces in the Mangala Vallis region.

The Mangala Valles is referred to in Michael Crichton's book Sphere. In Stephen Baxter's novel Voyage, it is the location of the first manned Mars landing.
