This cache IS at the posted coordinates. Please leave the container attached. You might need a tool to extract the log.
According to Geocaching.com, “The Unknown (Mystery or Puzzle) cache is a "catch-all" of cache types. This form of geocache may involve complicated puzzles that you will first need to solve to determine the coordinates. Mystery/Puzzle Caches often become the staging ground for new and unique geocaches that do not fit in another category.”
To qualify for this cache, you must have found and logged 100 Unknown (Mystery/Puzzle) caches. The statistics on your profile page will be used to verify your qualification.
There are challenges of this type elsewhere in Oregon. We felt there needed to be a set here in the valley. You can also find this challenge at GC2KAZ3 and GC34QP4.
We have tried to be consistent with the cache container as well as the cache location on all of our DJBACH CHALLENGE caches. Once you’ve found one, the rest should be easy. The hard part is qualifying to log the cache.
BRING TWEEZERS. PLEASE DON’T REMOVE THE INSERT. Each of these bison tubes contains an insert with the log inside. This is to insure that the log remains dry. When the insert is taken and the log is placed directly into the bison tube, it gets wet and can’t be signed.
