The Messinian salinity crisis (MSC), also referred to as the Messinian event, and in its latest stage as the Lago Mare event, was a geological event during which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago). It ended with the Zanclean flood, when the Atlantic reclaimed the basin.

With the glacial dam bursts in lakes Bonneville & Missoula, clear evidence exists of a fast, catastrophic flood. With this and the later filling of the Black Sea, views differ on whether the filling occurred catastrophically fast or was a more gradual process - am guessing therefore that the type of geologic flood scarring you see in Idaho would be, what - buried under sediment, or eroded by water?

Seabed features have been used in support of a mega-flood scenario for the formation of the English Channel.
