Ed - Let's Take This Discussion Off-list 08MAR2018
Ed you recently wrote,
>Paul, I am still not satisfied with your apology to Hibbens.
Given that I have not apologized at all and see no point to,
you are just going to have remain unsatisfied. For better or
worse, we are just going to have agree to disagree about
the need for an apology of any sort and continue any
additional discussion of this matter off list, which at least,
I will after this post. No need to torture innocent
bystanders with this tiresome discourse.
You also wrote:
>Paul, I am not satisfied with your apology to Hibbens yet.
>It is not fair practice in geology to point to something
>other than the formation the original researcher saw, and
>claim it was what he saw. That is simply bad practice, and
>highly unethical, and you need to own up to it.
Again, we have to agree to disagree as I stand by what I said
and do not understand what is unethical about pointing out
the problems with Hibben's research. If you truly believe
that I behaved unethically, then file a complaint with the
appropriate board(s) of registration for professional
geologists.
By the way Ed, there is a great podcast about interpreting
and misinterpreting myths and oral traditions, which you really
should listen to. It is:
The Importance of Myth and Oral Traditions - Episode 30
ArcheoWebby February 15, 2016
Also, Jason Colavito has some thoughtful posts:

Drumlin Formation Not Necessarily Evidence Of Catastrophic Event
Drumlin Formation Not Necessarily Evidence Of Catastrophic Event
People have selectively used the ideas of Dr. John Shaw to claim that they are undisputed indicators of catastrophic subglacial floods associated with extraterrestrial impacts. However, in their arguments, they completely either ignore over overlook any other research that strongly indicate that there is a lack of
any connection between catastrophic subglacial floods and drumlin formation. Some of this recent research is:
Observations from the surge-type glacier Múlajökull in Iceland underpin new modeling results that suggest the glacier's drumlins grow during quiet intervals of normal flow between glacial surges.

This might seem off-topic, but it might apply to vehicles used in the field for meteorite hunting.
Why Rodents are Chewing up Car Wires and What You Can Do to Prevent it.

Every farmer knows that vermin nesting in a warm engine bay is yesterday’s news. What is troubling is the growing volume of online stories about rodents chewing up expensive wiring looms that keep Audis, Hondas, Toyotas and Volvos running.
