This Geocache is solved in two steps. The coordinates lead you to the first cache (first step) in which you will find a key (this cache size is micro). There should be a hint in the cache that will lead you to a box (size small) with the logbook. Good Luck!
After you find it, be sure to put the micro cache away with the key and put the small box away locked.
This cache is available in the winter and snow boots are recommended.
