Man always kills the thing he loves, and so we pioneers have killed our wilderness. Many would like us to believe over-use is the fault of the early photographers who popularized the parks. The problems are more subtle, however, than they first appear. Overcrowding is one issue about which we can do little. The dilemma is in the hands of the Park Service for now.
Secrecy is no longer an alternative.
This is the information age. However, hiking guidebooks have done more harm than all of the collective wilderness photographs taken over the past several generations. The challenge facing us is how to help preserve what's left of our pristine wilderness environment. Sensitive natural areas and archaeological sites are of paramount importance in this fight. If you know of such an area, keep it to yourself.
