The mammoths liked to feed in the periglacial areas. By being right up against the glaciers the were shielded from the north winds, and the face of the glacier reflected sunlight back into the ground. The area near the glacier was much warmer than the surrounding tundra. It was well watered with melt water, and the soil was rich in minerals from the glacial till, and as loose as a well tended garden. Plants that are now exclusively tropical were better adapted to cold and variable day length.
Soooo, a mammoth feeds in the richest local environment, right up next to the glacier, and suddenly there's an avalanche instantly pounding the mammoth into the dirt and packing it in ice...
Well said.

[snip] One of the most amazing spectacles that I have observed is this: Those very men who observed and described the great catastrophes fall back and defend the theory of uniformity with even greater jealousy than their colleagues who never wavered and never were even tempted to question the ever harmonious run of centuries. Here is the case of Professor F. Rainey, presently with the University of Pennsylvania; him I quoted on p. I of “Earth in Upheaval” and please look up: “Wide cuts, often several miles in length” are sliced by giant machines in Alaska; “This ‘muck’ contains enormous numbers of frozen bones of extinct animals such as the mammoth, mastodon, super-bison and horse” (Rainey).
