I noted that the muck deposits indicate some sort of a gigantic process for which even a global flood might not suffice as a cause. Dwardu Cardona has proposed a radical explanation for them and that involves the Birkland currents associated with the antique solar system.

EARTH IN UPHEAVAL
Georges Cuvier, the great French paleontologist (1769-
1832), thought that in a vast catastrophe of continental
dimensions the sea overwhelmed the land, the herds of
mammoths perished, and in a second spasmodic move-
ment the sea rushed away, leaving the carcasses behind.
This catastrophe must have been accompanied by a pre-
cipitous drop in temperature; the frost seized the dead
bodies and saved them from decomposition. In some
mammoths, when discovered, even the eyeballs were still
preserved.
Charles Darwin, who denied the occurrence of con-
tinental catastrophes in the past, in a letter to Sir Henry Howorth admitted that the extinction of mammoths in
Siberia was for him an insoluble problem. J. D. Dana,
the leading American geologist of the second half of the
last century, wrote: “The encasing in ice of huge elephants, and the perfect preservation of the flesh, shows that the cold finally became suddenly extreme, as of a single winter’s night, and knew no relenting afterward.”
