Part of the Geocaching Creed mentioned earlier:

 

...Minimize My and Others' Impact on the Environment

This point wasn't brought up last week during the discussion regarding accurate coordinates. 

 

I have seen micros hidden in woods with log after log saying the coordinates are 50-60 feet off.  When you go to hunt those caches, you can tell everyone's coord (except the actual cache) were in the same spot. Then a 50-60 foot area is totally trampled and torn up. This is contrary to "leave no trace" and a good reason for having accurate coordinates.  Obviously, depending on what type of an area the cache is hidden in, the impact could be less or more.  A pavilion cache, for example, may have coord that just "take you to to the pavilion and now find it".  However, in an area where many people hunting will have an impact, "leave no trace" ethics would dictate the use of as accurate coordinates as possible.
