Jiake Zhou and three of his colleagues traveled 16 days on inflatable rubber boats in the northern Alaskan wilderness without seeing any other human, with nothing but a few guns and some pepper spray in case something went awry with the bears or moose they were surveying.
They traveled 568 kilometers on an epic journey along three connected rivers. But despite the excitement of close encounters with grizzly bears (Ursos arctos horribilis) and waking up to discover wolf (Canis lupus) tracks around their campsites, the team was concerned in large part about the shrubbery.
