Do Wooly Mammoths survive in the remoter regions of Siberia?  Below is a video taken by a Russian engineer while surveying for a road, of such an animal crossing a river.  Hoax, or confirmation that the mammoth still walks the earth?

And is that Bigfoot watching fromt the trees on the left? 

Since much of Siberia is basically unexplored, and mammoths did survive on Wrangel Island until about the same time as the Egyptians were building their pyramids, it isn't totally out of the realm of possibility, I suppose.
