These coordinates above are bogus, they are not an indicated start point nor are they used as a beginning point infact they are not relevent other than indicating that GZ is within 3km, you could go there if you want but beware of cars and please understand that there is no further hints or reference to GZ from this place.
GZ is not displayed on the satelite image below, its not in the park, and there is no point visiting, although I am told that there is an cache suitable stump in the park. You can visit the park if you like, I couldn't tell you much more about the park as I haven't been there..
Decrypt the coordinates from the image below to find the cache.

This is one of a few that I am planning around a general Orienteering theme..
It's not specificaly about orienteering, and thus if you know anything about this topic you have enough information to solve this puzzle.
