The population had the great coastal plains, now submerged and a couple of good zones in the Tropics.
For these conjectures to stand up and bark, there still has to be viable evidence. And in fact the evidence exists and is out there to be recognized. But without these conjectures in place and part of the mental tool box, all eyes are blind.
With these tools, it is now possible to look at old evidence and provide a superior interpretation. This will not always work, and the number of possible artifacts to be recovered decline rapidly as we go back in time. I also suggest that we should recall our own artifacts are nor surviving for very long at all and are now been vigorously recycled and will soon be all recycled unless they make it to an antique store.
As an example, my working conjecture on the presence of Bronze Age traders in the Mississippi valley has allowed a rereading of old reports whose evidentiary content could not easily have been fabricated at the time they were published and conform to established Bronze Age communities overlain on the indigenous societies. Now we need more informed eyeballs even if they are trying to prove that conjecture wrong.
There is evidence, controversial of course, from the time frames that matter and in the one place that they could be expected to exist. Scattered occurrences of unexpected artifacts have been found in mining locales. Most have a recent genesis as expected but a few simply do not.
The problem is sufficiently troublesome as to bring a whole range of aging methods into question. We are not just talking of the substantial readjustment brought to the science of carbon dating. Radioactive aging has always relied on the assumption that the process is independent of external effects.
If anything, the carbon fiasco should have cured us, but instead we actually have a situation in which the data is often fudged and ignored if it goes against prejudice. This means that although most dating is valuable, it needs to be confirmed by some form of physical method such as checking strata.
Aging is still a young science and we do not know what can alter radiometric readings although we certainly have evidence that it is possible. It is prudent to be overly cautious.
From my articles we have established that the crust shifted with the original pole migrating thirty degrees south along the longitude running through Hudson Bay. This shifted materials of the equator and led to compressive forces that lifted both the Andes and the Himalayas. It also led to a lot of additional alteration at the same time that we do not easily recognize.
One of those events may be the Columbia River basalt flows. It is actually the sort of thing that could have happened then. The studies on aging were saying that they were far older than that. And I would have been happy to simply leave it at there. Except human artifacts were then located below the basalt itself. When that happens, something has to give and ignoring the evidence is utterly unacceptable.
At which point everyone remembers that the basalts look fresh. That is also my beef about a lot of the mountains in the Andes and Himalayas and along the ring of fire. There are simply way too many surfaces defying gravity for a few million years to be very believable. If anything, the record shows an eruption of activity perhaps fifteen thousands of years ago followed be a steady settling down of such activity.
This also suggests that we should look to the Northern points of weakness and this quickly gives us the hyperactive Alaska volcanoes and Iceland by itself astride the crustal divergence rifts. Iceland likely was build during this era. The oldest rocks in Iceland are a meager 23,000 years, at least the last time I checked the literature.
It always amazes me that when you have a successful conjecture, how easily evidence falls into place. Right now we know specifically where to look.
I will make one additional comment. The early proponents of a crustal shift including Hapworth and Einstein opened the door to a couple of additional shifts which I dismissed as unlikely. With the advent of direct human causation, additional shifts become feasible and simply may have been necessary to achieve the final configuration that has given us the Holocene.
This is just a beginning. There are many reports out there that have been shelved that suddenly make a lot of sense if we are using my conjectures. If you see something in an odd location that I should see, let me know.
