Valles Marineris on Mars (see image below sent in by Michael) is 2500 miles long yet it is claimed it was carved out by water – but appears to be a straight line, or nearly so, along a good deal of its length.

Electric Universe enthusiasts think both have an electric origin rather than water flow. For example the Grand Canyon is dog legged (which requires explanation) and the fissures feeding the canyon resembel lightning streamers from the main channel of a lightning strike.
