Velikovsky, on the first page of his book, Earth in Upheaval (Victor Gollancz:1956) made some extraordinary claims of the so called Alaskan ‘muck’ deposits in the Tanana River valley, a tributary of the Yukon River - but where did he get his information from? He quotes Rainey (1940), University of Alaska, and FC Hibben (1943), University of New Mexico, but he obviously read a lot of other sources. One of them might have been Ralph Tuck, a geologist who first worked in Alaska on the railroad and then worked for a mining company - in which muck played a prominent role. In a paper in the Bulletin of the Geological Society of America, volume 51 page 1295-1310, (September 1940) ‘Origin of the Muck-Silt deposits at Fairbanks, Alaska’ Ralph Tuck gave his considered opinion how the muck was formed - and it formed quickly, by what he presumed was ‘outwash’ from melting glaciers (even though this part of Alaska was unglaciated). Hence, this article is in part a vindication of Velikovsky as outwash is not too different from the idea of a large tsunami wave roaring up the river valleys of Alaska...
“outwash...of a large tsunami wave roaring up the river valleys of Alaska...”
Or an outwash of melted glacier pouring out from mid continent as a huge bolide(s) strike in the Great Lakes area. I also hypothesize that great chunks of ice were thrown into the area of the Carolina Bays and similar structures where they skidded slightly giving the eliptical shape trending toward the Great Lakes and then melted leaving lakes of various sizes. All described in Firestone’s book.
