Two Canadian Wolves Visit Isle Royale NP but Choose not to Stay

According to John Flesher of the Associated Press, two wolves, a breeding-age female and a smaller individual --possibly her offspring-- visited Isle Royale National Park for five days this winter.  The two crossed Lake Superior from Canada over an ice-bridge during a hard freeze.

For wolf proponents, it was disappointing that the two did not stay in the park, as the small existing wolf population of Isle Royale lacks genetic diversity.

On the plus side, the visit confirms what scientists have long suspected; that Isle Royale National Park was originally colonized by wolves travelling across ice bridges.
