(NT) Found? Didn't know it went a missin'
Whew ! I'm relieved!
The discovery supports the theory that Earth's crust is constantly recycled deep into the planet as molten material from below simultaneously pushes up to refresh the surface.
"Refreshing the surface"
That's just fine with me.
(I agree about the carpet bit.)

Unfortunately, Angeline, those on the surface
may not feel so refreshed when millions and millions of metric tons of lava flow over it, as happened in the Pacific Northwest during the "Cascade episode:"
>> The Cascade Episode began as the modern ocean plate (the Juan de Fuca Plate) advanced into this area and was forced underneath the western edge of the continent. This gave rise to a chain of volcanoes that has been erupting here for the past 36 million years. Between 17 and 12 million years ago, great floods of molten rock erupted from cracks in the crust of Washington and Oregon to form the basalts of the Columbia Plateau. The modern Cascade Range has risen over just the last 5 to 7 million years. <<

(NT) But where is it-topside wise?
(NT) Somewhere in the Pacific Ocean
It all ties in with plate tectonics, volcanoes, ....
To tie this discussion in with a couple of others
Muchas gracias, senor Eduardo. Good article, interesting situation, hope everyone on the plate got off alright before it went down.
Kinda makes one wonder
If a large slice of the earth's crust can slide off the plate it would seem to give some credence to the Atlantis story.
