We often see evidence of life along the trail, but to see the result of our carelessness is an unplesant experience. Here is a pic which shows the pieces of a foil package not properly disposed of and which has been ingested and subsequently regurgitated by some critter. LEAVE NO TRACE is much more than a motto - it is a powerful statement of our presence in this land of beauty and when it (LNT) is practiced the words we here are "hey, no one has been here!" Thus, we are further inspired to seek out more beautiful places.
Keep hiking,
