The cache is NOT at the posted coordinates.
From the posted coordinates you need to find the stone marking the memory of two men who perished on a log drive. Using the date on the plaque you need to do some basic math to find the location of the container.
To find the north you need to take the day of the month and add it to the number of letters in the name on the right side of the stone. Add this to the north coordinates.
Then take the 2nd and the 3rd digits in the year adding them together. Subtract them from the west coordinates.
This will give you new numbers to find the cache. I hope you enjoy this spot. If there is much snow on the ground you will have difficulty finding this cache.
