A Differring View of Outflow Channels of Mars
A different viewpoint about how the outflow channels of
Mars was recently published. It is:
Leverington, W. D., 2011, A volcanic origin for the outflow
channels of Mars: Key evidence and major implications.
Geomorphology. vol. 132, no. 3-4, pp. 51-75.

Although I do not agree with this paper, it is interesting.
