Water-Rich Terrain

Caption

This three-dimensional image of a trough in the Nili Fossae region of Mars shows phyllosilcates (in magenta and blue hues) concentrated on the slopes of mesas and along canyon walls. The abundance of phyllosilcates show that water played a sizable role in changing the minerals of a variety of terrains in Mars's early history.
