Details Relating to the River Transport Theory
45. 
Away From Rivers, 
Yedomas and Loess,
Multi-Continental,
Frozen Muck,
-150°F,
Large Animals,
Vertical Compression. The river transport theory does not explain why frozen mammoths are often found far from rivers, why mammoths, yedomas, and loess are related, why these peculiar events occurred over such wide areas on three continents, why yedomas contain so much carbon, where so much muck originated, why muck has sometimes buried forests, why temperatures suddenly dropped to -150°F, why primarily the larger animals were frozen and preserved, or what compressed Dima and crushed Berezovka before or soon after death.
46.
Elevated Burials. Rivers would not deposit large carcasses on the higher levels of plateaus. A few mammoths are found 1,000 feet above nearby rivers.161
47.
Rock Ice. With the river transport theory, one would expect to find Type 1 ice, not Type 3 ice.
48.
Dirty Lungs,
Peppered Tusks. If Dima drowned, silt and clay might have entered his lungs, but not gravel. Nor would drowning distribute those particles within his intestines or embed “shrapnel” in mammoth tusks.
49.
Summer-Fall Deaths. How could so many animals, washed far north by rivers, get buried and preserved in hard, frozen muck? Even if flooding rivers buried mammoths under sediments that permanently froze the following winter, their bodies would have decayed after a summer or fall death. Besides, river flooding usually occurs in the spring, not late summer or fall, and rivers do not deposit muck. The organic component in muck would separate and float to the surface.
50.
Upright. Mammoths, transported by rivers, would not be deposited upright, as some were.
51.
Other/Fossils. No fossils of marine animals have been reported in deposits containing frozen mammoths.162
52.
Other/South. Frozen mammoths are not from the south, because their teeth and tusks differ considerably from those found in southern Siberia.
53.
Other/Float. Cold Siberian and Alaskan rivers would minimize the buildup of gas in a decaying carcass. This is why “bodies ordinarily do not float in very cold water.”163 Even if these remains floated for hundreds of miles, why were some found along very short rivers flowing directly into the Arctic Ocean?164 Why was their long hair not worn off? Why were frozen mammoths found on the New Siberian Islands in the Arctic Ocean, more than 150 miles from the mainland? Their bones do not show the wear associated with transport or water erosion. If an unusually strong river carried floating carcasses to these islands, the carcasses should have been found only along beaches. Instead, remains are found in the interior of islands, the largest of which is 150 miles long and 75 miles wide.165
54.
Other/Alaskan Rivers. Parts of six frozen mammoths have been found in Alaska, far from where rivers could originate even if temperatures were warm.
55.
Other/Swimmers. Elephants are, and presumably mammoths were, excellent swimmers.
