This is surely a very strange tale. In 1995 a family intending to camp in the white Mountains of Arizona were warned by a strange girl to come no further. They turned around and drove back, setting up camp later. Then, into the light of the fire, came a creature with no fur over its skin. It looked very thin and was the size of a bear. Its teeth, the witnesses noted, were sharp. It returned into the trees.
My suspicions are that this was a bear that had somehow lost its fur. A bear in such a state can look very strange.
