AI Thread Summary
The Messinian Salinity Crisis (MSC) was a significant geological event occurring between 5.96 and 5.33 million years ago during the late Miocene epoch, characterized by the Mediterranean Sea undergoing periods of partial to nearly complete desiccation. This event culminated in the Zanclean flood, which saw the Atlantic Ocean reclaiming the Mediterranean basin. The MSC is linked to various geological phenomena, including the catastrophic floods associated with glacial dam bursts in lakes Bonneville and Missoula, which provide evidence for rapid flood events. There is ongoing debate regarding the nature of the filling of the Black Sea, whether it was a gradual process or a rapid event. Additionally, seabed features have been analyzed to support theories of mega-flood scenarios, such as the formation of the English Channel. Notable geological formations, like Dry Falls in Washington and the Narrows under the Verrazzano Narrows Bridge in New York, serve as reminders of the scale and impact of these ancient floods.

TL;DR Summary
Much of the Mediterranean Sea dried up at one time.

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.

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'
(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
