NASA scientists have found evidence that thousands of massive ancient volcanoes erupted on Mars.

The so-called "super eruptions" occurred in a region of northern Mars called Arabia Terra over a period of 500 million years dating back approximately 4 billion years....

...Using images from the Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer, they studied the walls of canyons and craters from hundreds to thousands of miles away from the calderas, identifying volcanic minerals turned into clay by water.

They made three-dimensional topographic maps of Arabia Terra and compared mineral data to the maps in order to see that the layers of ash were well preserved....

...The question of how a planet could have only one type of volcano in one region remains. ...
