You found it.
No path on this trail leads here. No page links this one; the trailhead has never heard of it. You read a sitemap, or a source comment, or a line printed to a console at midnight — which means you are the kind of traveler this box was hidden for.
Letterboxing is an old trail custom: a hidden box, a logbook, a stamp, and the quiet fellowship of everyone who ever knelt at the same stone. This is the Waypost's box. The stamp is below; the logbook is the fireside.

|| what was not written to be seen
If you want the keeper to know you passed this way, leave an ember at the fireside containing the word clach — stone, in the Gaelic of the cairn blessing. Nothing happens when you do, except the only thing that ever happens on this trail: someone knows you were here, and does not forget it.
Now walk back the way you came, and mention this to no page.
