Welcome to Oakwood Cemetery in Allegan, Michigan.
Elisha Ely was one of the first white settlers in the area that is now Allegan, and his son Alexander gave land to the city for this cemetery in the 1830s. The cemetery was expanded in 1873. Buried in the spot behind Elisha are two of Alexander’s daughters.
To find the cache here, take Elisha’s age in months (you can drop the partial month) and divide it by 4. The answer, we’ll call it A, will be the bearing that you will need to travel.
Then take the years of the two granddaughters (Hannah and Elizabeth) birth and add them together. Divide that number by 3, and then subtract Elizabeth’s day. Just the whole number, drop any decimals. This, call it B, will be the distance.
Now project a waypoint from the posted coordinates B feet at A degrees. You will find the container in a familiar location once you get there.
