“Analysis reveals that, unlike typical, peat-rich Carolina Bays, Howard Bay essentially lacks peat, diatoms, pollen, and other organic materials, and it also lacks substantial silt and clay. That suggests this Bay never held water for a sustained length of time. Furthermore, the presence of extensive eolian sand calls into question prevailing hypotheses (a) that all Bays were lakes and ponds in the past and that their shapes were formed by wave action, and (b) that groundwater movement led to subsidence that formed the Bay. In addition, the presence of impact markers, including high concentrations of iridium in a layer just above the basal sediments of this Bay, supports the impact hypothesis for Bay formation. The age of Howard Bay appears consistent with and not older than the YD impact event; however, our research did not address the reported anomalous ages of other Bays, a question which remains unresolved.” Formation of Carolina Bays: ET Impact vs Wind-and-Water, Kobres, Howard, et.al., 2007 AGU
Hi Bob –
In one of the papers at this site, the Clovis peoples’ use of the Bays environments was hard documented with clear dated clovis artifacts.
(I believe I noted that at the time it was published here, if that’s of any help to you in locating it.)
Therefore the Bays existed before the Holocene Start Impacts.
An effort to try to recover more of the Oconachee and Yuchi memories of the HSI would run around $40,000, with no results guaranteed, as there is no way of knowing before looking what may have survived where.
The same costs go for memories of the Andaste, or better yet, a search for the lakes remembered by the Assiniboine as their location during the HSI. This last one would likely yield indisputable astroblemes.
Thank you for maintaining the archives of the Cambridge Conference.
George –
Looking at your graphic with the longitudinal cross-section of Howard Bay, I cannot but notice that all the ET markers are in the ‘fill’.
This HAS to be significant and instructive.
My first impression is that the ET markers came along after the bay was formed. Is there any reason to read that any other way?
