 Waters from the Vedra Valles, Maumee Valles, and Maja Valles went from Lunae Planum on the left, to Chryse Planitia on the right. Image is located in Lunae Palus quadrangle and was taken by Viking Orbiter. | |

The Maja Valles are a large system of ancient outflow channels in the Lunae Palus quadrangle on Mars.
Their location is 12.6° north latitude and 58.3° west longitude. The name is a Nepali word for "Mars".[1] The Maja Valles begin at Juventae Chasma. Parts of the system have been partially buried by thin volcanic debris. The channels end at Chryse Planitia.[2][3]
Huge outflow channels were found in many areas by the Viking Orbiters. They showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers.[4][5][6] The Maja Valles show evidence of lava flows in the northern section. Studies with HiRISE and CTX images suggest that the lava flows did not reach the turbulence necessary to erode large channels. So, the Maja Valles are believed to have been formed through water erosion.[7]

Great amounts of water were required to carry out the erosion shown in this Viking image of a small part of the Maja Valles. Image is located in Lunae Palus quadrangle.
