This cache was left by the Great Matthias and I. You don't have cross any tresspassing signs to find it. Check out the rocks.
It's a nice short hike with some cool views. Nearby is a building that many people see on a regular basis but few ever get near. I believe that they recently placed a fence around it to dissuade potential trespassers. Depending on how you come at it, the terrain rating will vary - but not to more than maybe a 3.5.
