The geocache *is not* at these coordinates, though, the posted coordinates are a great place to enter the trail.
To find the geocache, find the blueberry and walk 17 paces south-southwest.
The container holds a stamp that you can use to commemorate your find; do not take the stamp! You'll need to bring your own ink pad because they seem to never stay damp in geocaches (even if the geocache itself is damp).
