From the posted coordinates, follow a bearing of 48 degrees until you intersect the footpath. From that point, follow a bearing of 50 degrees for 102 meters. Then you will arrive at the coordinates of the cache. You are looking for a nano. If you need help, check the hint and test your final coordinates with the geochecker provided below (which is currently only available on the web). If you're going to try it by doing the math, consider converting to UTM coordinates.
This cache was inspired by the Pi Day Cache in Soap Lake, WA. You can view that cache here: GC5NNZN Pi day Cache
Have fun caching!
