The heads of canyons — the parts of gorges created by the downstream waters of a river — can have a variety of shapes. At times, canyon heads can resemble amphitheaters — the heads are curved when seen from above (think Niagara Falls), and the walls of the canyon heads rise straight up vertically.
"Amphitheater-headed canyons are relatively rare on Earth, but they abound on the surface of Mars," Lamb told LiveScience's OurAmazingPlanet
...
Unexpectedly, the researchers discovered the amphitheater-headed canyons of Malad Gorge formed at the same time as the amphitheater-headed Box Canyon, about 11 miles (18 kilometers) to the south — about 46,000 years ago.
These findings, detailed online Dec. 16 in the journal Proceedings of the National Academy of Sciences, suggest these amphitheater-headed canyons were formed by the same flood, "and that this flood must have been truly extraordinary in scale," Lamb said. The research team calculated that the flood was at least 30 feet (9 m) deep, flowing at a rate of at least 330,000 gallons per second (1.25 million liters per second).

Not to mention 2 meters of ash in a number of surrounding states, perhaps as far as the Mississippi.
You know that Europa is orbiting Jupiter, right? Nowhere near Mars.
The fertile soil of the Willamette Valley was once the soil in Eastern Washington. Flushed down the Columbia River Gorge, and backed up a couple hundred miles.
I can’t imagine any technology we’d ever develop capable of moving any of Jupiter’s moons anywhere but right in to Jupiter itself.
Once locked in to that giant’s embrace there is no force within the grasp of humanity that could move something so massive as a moon, nor send it out of the grip of Jupiter’s awesome gravity.
Even less likely would be our ability to target it’s movement well enough to drench tiny Mars without sending the moon careening on a crazy orbit to God knows where.
Perhaps in science fiction, but impossible in reality.

I was being ironic. “Illustrating absurdity by being absurd,” as Rush would say.
I’m getting old and dense I guess.
It’s not your fault. Irony doesn’t always work in text form, as I’ve found out many a time.
