Boundary Waters Canoe Area Wilderness, MN

The million-acre BWCAW is the most heavily used wilderness area in the US, and has been the subject of long-term studies of forest fire and windstorm impacts on boreal forests. The BWCAW was listed by National Geographic as one of the original "50 places of a lifetime."
