The Pleistocene Extinction

djf, my original post was purely in jest.

Then, about 1950, they started mapping the ocean floor and discovered the mid-atlantic ridge. They finally had to accept his theory, but instead of calling it "Continental Drift", they called it "Plate Tectonics"

This did get my attention. I have had, and still do, a keen interest in geology - started when I moved into an area that was "hot" - Nevada - 20 some years ago.

I make no claims to expert knowledge, but I know enough that the Feds intent to carry on with Yucca Mountain is truly stupid. Several "go arounds" on this forum with other folks - all well east of here, curiously enough :) - that think all their nuclear waste should go to Nevada.

The ignorant are, sometimes, blinded by their stupidity.

As for your link, I thank you. Book marked and will be reading about soon.

When the idea that the current continental configuration was indeed "fluid" was first published - it was shunned.

Then it was proved. Pangea (sp ?) to what we have now - ever changing, etc.

Again, I am fortunate to live out west - where it's happening - seismically speaking.

I think there are about 20 people in this town that know there is an "extinct" volcano in the mountain range that borders the east side of this valley. Or know about the "Long Valley Caldera" on the California / Nevada border. The last time it blew it covered this area in 6" of ash - and that event was not all that long ago, in geologic terms.

I poked fun with my first post. No offense intended. I do apprecitate the link you sent.

Come on up to Puget Sound for some active geology and volcanism. Just be careful where you stay - they aren't going to issue warnings to some towns now since there won't be time to evacuate.

I like the signs down near the coast "Tsunami escape route".
If there was a tsunami, the first guy on the road would be some geezer with a bum hip in a '63 rambler that would blow a rod half way up the hill!

Talk about traffic jams...

[djf]

They just had another event near Portland, a 2.2, that makes 5 today.

I hereby declare that the new volcano in the pnw is named "Mt. djf"!

Only the small ones fit in the first Ark. They had to leave the big ones behind. :)

Interesting.

Well thank you for the invite - but I have to decline - for health reasons.

Seems that awhile back they found evidence (trees buried under several feet of sand) of some rather sizeable tsunamis in your locale.

Tsunamis are a given fact if you live close to the ocean. The problem with your area was that they found this evidence about 100 miles inland from the coast.

I may not be the brightest bulb in the "illumination" scheme but that tells me there was one hell of shake immediately off your coast.

Indeed, evidence points to repeated occurances of these events. Tick..tick..tick.

Your player is the Juan De Fuca plate. As - literally - opposed to the North Amercian and Pacific plates.

As a matter of fact, there is a new and growing volcano not too far off shore from you folks - forget the name they gave it - but of very high interest.

Of course we can't ignore the stuff to your west - Mt Hood, Mt Baker, Mt St Helens, etc.

The Rim of Fire.

What does not get enough publicity is the fact that the more these volcano's age, the less stable they become. Acidity from the volcanic gasses literally turn stone into clay.

Nevada ranks second in the "thin-ness" of the outer crust - what my house sits on. This state is literally being pulled apart - like you pull a pizza dough to spread it thin.

Again, thank you for the invite but I think I'll be staying here.

Everything west of the central valley in California sits on the pacific plate. Most know about the San Andreas fault, but there are a number of faults that run basically east-west. The crust is being thinned, California is being sheared in half, it is a rift valley, expect the Baja peninsula to grow as LA becomes an island.

Landers - North Ridge - we felt them.

Landers - stero speakers suspended from ceiling swaying, water in my pool - side to side waves - spilling out. I have a water bed. I was ready to bitch at the wife, "what the heck you doing over there?", when I noticed she was still asleep.

Won't be long before San Fran is in Alaska!!! Ha.

Yup. You'll own either very expensive oceanfront property, or you'll need a houseboat!

The evidence for crustal shift has been growing, but the most important evidence to explain events like 11,600 years ago doesn't come from the bone fields (which are massive, there is still literally hundred of tons of mammoth ivory in the Siberian Steps).

The evidence comes from a volcanic ridge in Eastern Oregon called Steen Mountain. Two geophysicists, Coe and Prevot, went there to study the lave flows from an eruption that happened a few million years ago. They mapped out the tubes of the lava flows. They then drilled the lava flows to test composition and geomagnetic alignment.

In ten days, the magnetic field of the earth shifted 45 degrees. In two weeks, the total shift was 60 degrees.

In the two weeks mapped out, the magnetic pole of the earth shifted over 4,000 miles.

The data is incontrovertible. Something astounding happened. Something modern science doesn't have any sort of explanation for at all.

My theory is that this epoch ending occurrence was caused by:

Southwesterly:

Umbrian:

Vibratory:

Striations

"They just had another event near Portland, a 2.2, that makes 5 today."

I was in the North Ridge earthquake back in '94. We had numerous small earthquakes in the 2 range off the coast of Santa Monica for a couple of weeks before it hit. Not to get you worried or anything...8-)

Djf, dude - or dudette - you are my new best friend - geologically speaking.

Are you from / in the north west? Not that that is important. Just curious.

People freaked about Mt St Helens when it blew. That was nothing but a sparkler show in a serious fireworks demonstration.

Mt Mazama. That was big. Memory - probably wrong - tells me that event was about 11,000 years ago. Yellowstone National Park. That was big - several times. A caldera of huge proportions - and now growing - again. Reload.

I have not heard of Steen Mountain - it has actually been several (5 -6) years since I've been actively looking / reading. etc.

Have you been to Idaho - Craters of the Moon, etc? Snake River Plateau, etc?

Several documented cases of the the magnetic fields completely flip-flopping. All from looking at lava. Amazing stuff.

The trouble with the scientists is all they say is "That's normal seismic activity" over and over till something happens, then they say "That one wasn't!"

Guess if we want predictions, we gotta call Miss Cleo or somethin.

[djf]

The longest and most grande physical feature on Earth is the mid-oceanic ridge, a chain of mountains running some 40,000 miles long.

I've spent the equivalent of weeks 1,400 feet underground in an active gold mine, so I know a little about rocks. (besides the ones I have in my head)
