From what size predator, would a wooly mammoth have needed to evolve an ability to hide?

I think early man hunted them, IIRC.

From that largest and most voracious of all predators, global cooling. Those with the lighter fur did better at the glacier edge while the darker furred animals roamed in warmer climes. /total conjecture

Ebola's on the small side...

Then there are the animals that attack in packs. Get inside, and under the 12ft+ tusks, and it was probably
vulnerable, especially from *all* sides. I'm thinking hyenas, coyotes, etc.

Uh, humans and dire wolves and saber-toothed tigers, perhaps. Humans were the most dangerous predator of the wooly mammoth, though.
