After a long day on the trail, the last thing you want to do is pick up another's rubbish, find an illegal fire ring, or even worse, step in the remains of someone's personal bathroom. Everyone who heads into the wilderness can benefit from and practice the "leave no trace" ethic. Developed by the National Outdoor Leadership School, this outdoor recreation philosophy emphasizes moving through the land gently so that your trace disappears as quickly as you do. To this end, Annette McGivney offers helpful techniques for low-impact hiking, paddling, camping, and cooking that will enlighten first-time trail users and refresh the minds of seasoned outdoors enthusiasts.
