Geocache Description:

This is not an easy trigpoint to visit and will require planning, suggest you consult trigpointing UK and Hill Bagging to find your own route and match this to your ability. Whatever direction you take, it will involve a long stretch over pathless heather and some bog. It seems most walkers use a route from Mill of Lyne Bain and then across footbridge

About Ye Ole Survey Monuments

Ye Ole Survey Monument (YOSM) is a captivating series of caches that pays homage to the remarkable legacy of OutForTheHunt's YSM series (GC45CC).

YOSM caches are strategically positioned at or near Trig Points. These triangulation stations have played a pivotal role as surveying landmarks, contributing to the mapping of expansive territories.

Some of these points, bearing historical significance, might now be situated on private land or have vanished with time. As a result, the caches are artfully placed in close proximity, reverently acknowledging the historical importance of these survey monuments.

More information, bookmarks and statistics can be found at the YOSM Website

If anybody would like to expand the Ye Ole Survey Monuments Series, please do.
I would ask that you request a number for your cache first at
so we can keep track of the numbers and names to avoid duplication.
