When a great deal of Earth’s water was locked up within mountains of ice, our ancestors scampered across a dry corridor from what is today Siberia over to Alaska. Those adventurous souls may have been accompanied by another creature that needed wood — the moose.

That is the notion of Pam Groves, a scientist who recreates ancient landscapes at the University of Alaska Fairbanks. She recently wrote a paper on moose occupation of Alaska’s North Slope based on ancient moose antlers and bones she has found during decades of floating northern waterways. Dan Mann and Mike Kunz co-authored the paper.
