Exaggerated Reports of My Demise
event November 7, 2012 comment 10 Comments

E.P. Grondine was kind to contact me this morning with a thoughtful “Is everything OK?” query.  Emphatically yes, and that is the problem.  My business and civic life, as balanced with young family, have been all consuming for me of late. Our company just signed a very, very large contract and I have recently been appointed Vice Chair of the newly formed North Carolina Mining and Energy Commission, charged with the writing an entire set of on-shore exploration and production regulations for our state — from scratch — over the next eighteen months. Throw that in with a griping election season (recall I am a politico), and no particularly interesting news on the catastrophism front, and the wind just got sucked out of my hobby: the Tusk.

But none of that is really an excuse for ignoring a subject of existential importance for two months with nary a word.  If we were blogging on “flowers” or “pets” that would be one thing….

What I need to do is pick through the last few papers, find some interesting and under recognized aspects (since no one really reads papers), and give them some play. Hmmm…. I will also take nominations along those lines (or other truly compelling subject matter).

Thanks for your patience.

  1. Here’s one for you George. The full text of this thing is behind a pay wall. But since your livelihood is all about wetlands, this negative shot across the bow of the YDIH is something that deserves the Tusk’s attention

    Accumulation of impact markers in desert wetlands and implications for the Younger Dryas impact hypothesis

    Abstract:

    “The Younger Dryas impact hypothesis contends that an extraterrestrial object exploded over North America at 12.9 ka, initiating the Younger Dryas cold event, the extinction of many North American megafauna, and the demise of the Clovis archeological culture. Although the exact nature and location of the proposed impact or explosion remain unclear, alleged evidence for the fallout comes from multiple sites across North America and a site in Belgium. At 6 of the 10 original sites (excluding the Carolina Bays), elevated concentrations of various “impact markers” were found in association with black mats that date to the onset of the Younger Dryas. Black mats are common features in paleowetland deposits and typically represent shallow marsh environments. In this study, we investigated black mats ranging in age from approximately 6 to more than 40 ka in the southwestern United States and the Atacama Desert of northern Chile. At 10 of 13 sites, we found elevated concentrations of iridium in bulk and magnetic sediments, magnetic spherules, and/or titanomagnetite grains within or at the base of black mats, regardless of their age or location, suggesting that elevated concentrations of these markers arise from processes common to wetland systems, and not a catastrophic extraterrestrial impact event.

  2. George,

    How do we know you’re not actually running Tusk from the afterlife?

    and

    what is the flaw in the above paper? I briefed through it but not the supporting papers and couldn’t find anything glaringly wrong. But I’m not an Earth Science type either, so there’s that.

  3. because I am actually responding this time. Although there may be Touring Machine concerns.

    Anyway, I am working on several posts and fronts. I am particularly interested in the 1000AD tsunami that hit my own coast. Anybody remember that post? That was great stuff!

    Pigati too…

  4. probably not this tusnami paper (based on psychic prophecies resolved through “remote viewing” meditation….!) Please excuse me if I don’t capitalize “remote viewing”….

    or here is a page with goodies:

    including this cool movie:

    and this hit west of Ireland

    OR

    maybe this Canary Island collapse Tsunami paper which, with its “puny” terrestrial cause is only 100 meters peak to peak in the near field from the source:

    “Tsunami deposits in the geological record”

    OR
    this book on various precambrian impacts, with some great graphics including the one in the Shuvalov paper on page 326 that shows a 200 meter diameter stony impactor at a mere 15 km/sec making a ~2 km deep water crater in a deep water case….

    still, none of these is the one I was looking for.
