4 - Puzzling 101 Mystery Cache

The Cache is NOT at the published coordinates

This is part of the Puzzling 101 series of caches designed to give a brief introduction to some puzzle (unknown) caches over a walk of less than 2 miles (60 to 90 minutes depending on search time)

Once FTF has gone on all caches I will add Parking and a Route Map

Puzzling Puzzles

Puzzles can also take a more traditional puzzle route, using brain teasers, crosswords, word searches etc. Depending on the complexity of the puzzle there may be some guidance as to how to "extract" the final coordinates, such as North AB CD.EFG

Your turn :)

North:
... 46 48 50 ?? 54 56 ...
... 64 81 1?? 121 169...
... CDXXXVIII CDXXXIX ???? CDXLI CDXLII ...

East:
