Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Vallis (plural valles) is the Latin word for valley. It is used in planetary geology for the naming of landform features on other planets. Vallis (plural valles) was used for old river valleys that were discovered on Mars, when we probes were first sent to Mars. The Viking Orbiters caused a revolution in our ideas about water on Mars; huge river valleys were found in many areas. Space craft cameras showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers. Nirgal Vallis is one of the longest valley networks on Mars. It is so large that it is found on more than one quadrangle. Scientists are not sure about how all the ancient river valleys were formed.
