Megafloods in Idaho and on Mars
December 26, 2013 | Caltech
"South-central Idaho and the surface of Mars have an interesting geological feature in common: amphitheater-headed canyons. These U-shaped canyons with tall vertical headwalls are found near the Snake River in Idaho as well as on the surface of Mars. Various explanations for how these canyons formed have been offered—some for Mars, some for Idaho, some for both. [...] Kenneth A. Farley offers a plausible account that all these canyons were created by enormous floods." Quoted from the Caltech press release.
