White. It was a polar bear.
Assuming he never had to travel east, then he camped on the north pole, meaning only a polar bear could've destroyed his camp
Then he could've walked in a circle in the Rocky Mountain or Canadian wilderness, meaning it could've been a brown, black, or grizzly bear.... Or it there was no trees and only tall grasses, it could've been a giraffe. The lack of true directions pretty much invalidates the premise.....
1017225: Cardinal directions are given. The standard procedure for following such directions are along meridian lines for north/south and along parallels of latitude for east/west. Now, knowing this, back to the op.... Nobody has effectively explained why it is at the North Pole yet.... (HINT: Are there any other places on the Earth where such traveling can be accomplished?)

Fine, I'll explain. At the north pole, you can ONLY go south. Once there, going east or west follows the lines of longitude which is perfectly perpendicular to the north south line. Once at the next point, a path straight north leads back to the pole. Is it really necessary to do the geometry? The intuition is readily apparent with the answer.
