Recalibrating the Alaskan muck produces some familiar dates!
Alaskan Muck Dating
In 1941 Alaskan muck was thought to originate in the “late Pleistocene or Early Recent”.
The typical Alaska “muck” is described by Mertie as a dark gray to black silt, principally derived from the underlying schist bedrock, containing a considerable quantity of vegetal material, lenses of ice, and strata of peat and volcanic ash.
These silt or muck deposits are eternally frozen three feet below the surface.
Tuck differentiates between silt and muck pointing out that the silt occurs only on the sides of the valleys and is unfrozen.
Many of the local miners refer to these side valley deposits as “dry muck.”
The muck blankets considerable portions of the interior of Alaska in thicknesses varying from four or five feet to over 100 feet in the vicinity of Fairbanks.
These muck deposits and accompanying sedimentary depositions are regarded as late Pleistocene or Early Recent in date and overlie older Quaternary gravels.

By 2017 Settled Science had produced an impressive collection of megafauna extinction dates that graphically fall within an Overton Window covering 8,000 to 50,000 years ago.
The Overton window is a term for the range of ideas tolerated in public discourse, also known as the window of discourse.
Unfortunately, these Settled Science dates represent a Dating Debacle.
Quarter-Baked Time Two
It’s valid to describe the radiocarbon dating of mammoth bones as half-baked provided it’s understood the dating has been [at least] quarter-baked twice over.
The first quarter-baking is the extraordinary roller-coaster calibration curve.
Whatever is happening here, it’s likely linked to their Glacial Maximum definitions.
The second quarter-baking is the latitude issue that produces problematic polar dates that reflect latitude [i.e. not age].
The only significant differences between Then and Now are found amongst the fragmented flora and fauna in the frozen Alaskan muck.
Luckily, the 2017 Alaskan muck assemblage [above] includes a GICC05 δ18O ice-core trace that can be recalibrated using Leona Libby’s Old Japanese Cedar Tree chronology [below].
The Libby alignment suggests the Greenland Ice Sheet is about 1,100 years old i.e. exactly the same age as the ice on Iceland.
The recalibration of the 2017 Alaskan muck assemblage adjusts the original range of 8,000-50,000 years BP down to 520-975 years BP aka 1430-975 CE.
The recalibration indicates the Younger Dryas is the Hecker Horizon.
Gradualist academics have unwittingly documented [in some detail] a catastrophic event that left an indelible mark – the Hecker Horizon – upon the Earth’s surface during the 14th century CE.
And the Hecker Horizon represents the final megafauna extinction event.
Moa were nine species (in six genera) of now-extinct flightless birds endemic to New Zealand. … Moa extinction occurred around 1300–1440 ±20 years, primarily due to overhunting by Māori.
An extensive ancient archeologic site containing lithic artifacts and associated with mammoth remains was reported at Chinitna Bay, southern Alaska in 1943.
Geologic studies and radiocarbon dating indicate that the strata reported at the site are intertidal in origin, very late Holocene in age, and have undergone significant tectonic movement in the recent past.

Thereafter, Earth Science boards the B-Ark for it’s Quaternary Cruise.
Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth’s paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples.
The MIS timescale was developed from the pioneering work of Cesare Emiliani in the 1950s, and is now widely used in archaeology and other fields to express dating in the Quaternary period (the last 2.6 million years), as well as providing the fullest and best data for that period for paleoclimatology or the study of the early climate of the Earth, representing “the standard to which we correlate other Quaternary climate records”.
Quaternary … spans from 2.588 ± 0.005 million years ago to the present.
The useless third of the population (consisting of hairdressers, tired TV producers, insurance salesmen, personnel officers, security guards, management consultants, telephone sanitisers and the like) were packed into the B-Ark, one of three purported giant Ark spaceships, and told that everyone else would follow shortly in the other two. The other two thirds of the population, of course, did not follow…
Having waved goodbye to Settled Science it’s time to get back to Frank…
