Transplanted wolf that went back to mainland from Isle Royale NP wandered exceptional distance

ISLE ROYALE, MI – Two years ago this winter, after an arctic blast had frozen the surface of Lake Superior between Isle Royale and the Canadian mainland, a 4-year-old female wolf walked to the edge of Michigan’s most remote island after sunset. She took a few steps onto the ice … and kept going. About 15 miles later, the 70-pound wolf who sported a distinctive black fur mantle across the back of her tan coat, stepped onto the Canadian mainland, her GPS tracking collar showed.

And with that one freezing, unexpected walk on Jan. 31 2019, the wolf known as W003F largely took herself out of the world’s longest predator-prey study that’s been going on for decades on Isle Royale.
