good stuff
so I went to you tube

I like it when the narrator says:

A meteor the size of the Hiwatha Impact
Is unlikely to occur in our time

But evidence of finding this crater
Is proof we shouldn’t let our guard down
Ha

Vegasjames, when oil or gas wells are being dug the drilling company will change the drill bit to a core bit to collect samples for where the seismic data and mud/gas inspection from the hole indicate the possibility of hydrocarbons. When I taught science in Sonora, Tx. my students would bring in bore sample cylinders from wells that were being dug for the geology section. The process is nothing more than a procedure for direct data collection.

if I was younger James I might have gotten the terminology correct

\According to wiki
In Biology Dryas refers to a certain Flower

There is also a type of monkey called a Dryas in the Congo

In Greek language Dryas may mean- Oak
There were even several mythological characters in their Myths called Dryas

In geology Dryas are designation for climatic periods
Some of those periods include:

Old Dryas
Older Dryas
Middle Dryas
Young Dryas

The Dryas Impact Theory postulates
That around 12,000 years ago
there was a meteor strike
in the northern hemisphere
during one these Dryas Periods

which caused the extinction of much of North America’s
Mega fauna .

Finding that impact crater,
as been one of the proofs geologist’s have searched for
to verify the theory.

Perhaps the Hiawatha Crater is just this proof?

So recovering more data is a goal
Although as we know
precise dating of past things
is very contentious…
