You will need to collect seven clues to learn the coordinates of the cache. Each clue will suggest a piece of the final coordinates. The following six puzzle caches contain the first six clues, written on the log and/or taped to the inside of the container.
The seventh clue is "Millard Fillmore, 1856".
The posted coordinates for three of the seven caches in this series are located at a college; the final coordinates for three more of the caches are located at a college; the remaining cache requires detailed knowledge of a 230-year-old college.
Some of the puzzles can be solved from the comfort of your home, and some require that you get out and about.
The six caches listed above are all urban caches. Your reward for solving Educational Enigma will be a short walk on an easy trail.
Have fun!
