> Over a period of 36 hours, tens of thousands of workers pulled the spikes from the west rail of all the broad gauge lines in the South, moved them 3 in (76 mm) east and spiked them back in place.[6] The new gauge was close enough that standard gauge equipment could run on it without problem. By June 1886, all major railroads in North America, an estimated 11,500 miles (18,500 km), were using approximately the same gauge. To facilitate the change, the inside spikes had been hammered into place at the new gauge in advance of the change.

Other scientists: Mars is dead. It can't tectonic.

This paper : Whoo-hoo-hoo, look who knows so much. It just so happens that Mars here is only MOSTLY dead. There's a big difference between mostly dead and all dead. Mostly dead is slightly alive. With all dead, well, with all dead there's usually only one thing you can do.

Other scientists : What's that?

This paper : send rovers across the planet and look for loose change.
