Special tool required.
Look around at the published coordinates for the information you need to find the coordinates of the cache.
Part of a mini-series of caches; all of which require a (different) special tool.
You must record your caching name when you find the coordinates of the cache and sign the paper log in the cache to be able to log online as "Found". I reserve the right to delete your online log if you haven't done both of these.
This is a Historic Geocache.
