in a weekly evening gathering at SF Complex for shared discussion.

If it is ok to take a firm stand on one side of the debate, or the other,
I'll cast my lot with Dr. Firestone, and friends.
I was trained to do battle damage assessment in the military.
And it has been an interest ever since.
A long time ago, when the first LandSat images became available to
the general public, I noticed some explosive blast effects in the
southwest US, and central Mexico that couldn't be believably
explained by standard theory in the light of the new hi-res
satellite images.
At the time I knew nothing of any work on the
Younger Dryas cooling.
And it was long before anyone had proposed fragmented
comet impacts.
But it was a wonderful conundrum.
I knew I was looking at the ground effects of an unimaginably
violent event that flew in the face everything I had ever learned.
And I knew of no natural energy release to account for them.
For that matter I knew of no kind of natural energy release at all
that could do what I was seeing.
The ground effects, and blast effected materials, I had noticed all
seemed to point to something that happened around the end of the
last Ice age.
And, when I learned of work on the Younger Dryas Boundary layer,
and the nano-diamonds R.B. Firestone et al, and others had found
there, I realized they confirmed some of what I had found.
It confirmed, if nothing else, that an event of the level of destruction
I was looking at did indeed happen.
And recently enough too.
>From what I can see R.B. Firestone et al are spot on.
There is no end to the theories related to to the so called
Younger Dryas impact event.
Some are good, and some not so good.
And I've no doubt, you have heard them all by now.
But here's a fresh viewpoint that looks at the actual ground effects of
such an event from a fluid mechanics / blast analysis point of view:

photos, some stereo images, and a few short videos



The Benavides Impact Structure
The explosive process that did this has never been studied before.

The semi circular ring of  The Benavides Impact Structure is 17 miles
Just accros the border from Terlingua, Texas, and Big Bend
National Park, USA.
The perfect semi-circle was the first anomalous land form I noticed
in the satelite images.
It was obvious that it is the result of a violent explosive event that
standard theory can't properly describe.
And my obsessive curiosity wouldn't let me leave it alone.

The maps show this area to be volcanic due to the melt formations.
But there is no volcanic vent here so the violence did not come from
The 17 mile ring, as well as the smaller, overlapping, 8 mile wide
impressions are all perfect circles incised into the surface from above.
The mega-breccias and ignimbrites outside the structure were blown
there by a great force of heat and pressure which scoured everything
from inside the circles and cut into the surface like a giant cookie cutter.
And the heat inside the circles was enough to re-weld the fractures
in the rock.

Here we begin to see some of the clear evidence of the predominant
southeast to morthwest direction of the impact firestorm in the
directional nature of the breccias, and other blast effected materials
of this structure.

Outside of the southeast edge of the structure, the pressure driven,
blast effected, materials were thrown into the super-sonic impact
wind so they piled up outside the compression wave of the explosion
in a standing wave of mega breccias

The breccias are heaped 800 to 1000 ft high.

On the opposite side, outside of the northwest edge of the  structure
are repeated blankets of ejecta, and ignimgrites thrown down wind
10 miles, or more.

The melted material did not come out of the ground.
There is no vent here.
Whatever the heat source may have been it was not volcanic.
The melt blankets of ejecta, consist of the original surface terrain,
flash melted from above, and quickly blown off, and away,
from its points of origin.

 The white line in the bottom left is 1 mile for scale.

These are stereoscopic images.
Click on them for an enlarged view.
To see the 3D effect simply focus on the center line, and cross your
eyes a little, until a 3D image seems to appear in the middle.

Looking down to the southeast from about 45 km up.

The inter-fingering patterns of movement, and flow in the edges of
these blankets of melt are consistent with sudden emplacement
like impact melt ejected from a crater.

Looking west, down the valley formed by the ring, we see the
mega-brecias on the up-wind side of the structure.

Volcanoes don't do this.

The planetary scaring of the Younger Dryas impact event.

"...Our impactors  appear to have been a large,  highly fragmented,
and loosely grouped, cluster, about 500 km wide, like a giant,
flying gravel pile.
The thing would have looked like a sister to the images of the
fragments of comet Linear seen here.
It came in at very high velocity, and low angle of approach from
the southeast.
And almost all of the fragments exploded above ground like
Except that, in Mexico, only the very first of the fragments on the
leading edge fell into cold  atmosphere.
The rest fell into already super heated impact plasma, and just
added to the heat.

The primary impact zone is a 500 by 1300 km oval that covers
most of north central Mexico.
And extends well up into west Texas, and New Mexico.

The other impact zone is a little smaller in the great lakes region.
And it extends from northern Minnesota, well up into Canada...."

A Different Kind of Catastrophe

This entry, I would like to introduce a guest writer -- Dennis Cox.
I was very impressed with his theories of a Different Kind of
He not only comes through with a new theory, but research
to back it up
Please give him an opportunity!
And Thanks, Dennis, for a very well written article.

"...In New Mexico at the northern edge of the primary impact zone
there are crater fields with too many craters to count about the size
of a football field.
They are on the other side of the state from any ordinance testing.
And they are described in the maps, and literature simply as
"enigmatic depressions".. Let's see, perfectly round, punched
into the surface from above, yep! pretty darned enigmatic to me.
But only if you don't believe in giant, geologically significant,
multiple fragment, thermal impact events.

I've also cataloged more than 700 non-standard impact structures
that are more consistent with the hot, and powerful, surface
detonation of a shaped thermal explosive charge than anything
from we thought we knew about impact events, or possible
compositions of bolides.

Depending on the strength of the surface, and the size of the
detonation, the blast burns grade from a deep, thermal burn
to a full fledged crater.
And they are square.
That's right, I said square, with a capital "S", square.
No two are exactly alike.
And the ones that only show a thermal blast burn without excavating
a crater make it clear that the square shape is a product of the
detonation burn pattern.
Not the result of patterned fracturing in the surface rock.

Here are links to the image set of square blast burns, and craters,
in roughly 100 image, gallery segments.
As well as a few ordinary round ones.
They are in no particular order, as they were saved pretty much in
the order they were found.
There may even be a duplicate, here and there.
And this is by no means a complete inventory of them.

1 to 100, 101 to 200, 201 to 300, 301 to 400, 401 to 500,
501 to 600, 601 to 700 and Crater Field.
(These last two galleries are a work in progress)

5 pages of 20 large color Google Earth images of craters # 1 to 100

I'm still hoping for a seasoned physicist to weigh in on them.
So share them around as you see fit...."
