Scientists say the main feature, known as Drop 45 Drive Lane, is the most complex hunting structure discovered beneath the Great Lakes to date. The 9,000-year-old limestone structure consists of two parallel lines of stones that lead to a cul-de-sac lined with natural cobblestones.

Nature will do what it wants, so I can't speak for the wolves. Humans on the other hand, at least in US and Canada, operate under North American Model of Wildlife Conservation, whose core principles are elaborated upon in the seven major tenets:

* Wildlife as Public Trust Resources

* Elimination of Markets for Game

* Allocation of Wildlife by Law

* Wildlife Should Only be Killed for a Legitimate Purpose

* Wildlife is Considered an International Resource

* Science is the Proper Tool for Discharge of Wildlife Policy

* Democracy of Hunting
