As part of the Ye Ole Survey Monuments (YOSM) Series 1st Anniversary celebrations on 18 April 2025, geocachers around the UK are invited to host and attend YOSM-themed events. These events will help mark the incredible journey of trig point hunting and the historic retriangulation of Great Britain.
This event will take place at Penistone Hill trigpoint, near Haworth in West Yorkshire. Clicking on the trigpoint name will take you to the relevant page on the Trigpointing website. This link is not associated with geocaching.com and is not a website belonging to me.
Penistone Hill Country Park has a large car park on top of the hill, and there are other smaller car parks nearer the main road. The trigpoint is a 5-10 minute walk from the car park along relatively flat, but uneven paths. The paths are typical of moorland areas.
Penistone Hill Country Park has a set of labs and a few other caches as well. One of the labs is at the Trigpoint itself.
I will be at the trigpoint between 12pm and 12.30pm on Friday 18th April.
Trackables - any which fit into a small tupperware box (with the lid on) are welcome. If you wish to bring anything larger, you are responsible for passing it along or taking it back if no-one is willing.
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.

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 www.yosm.org.uk
so we can keep track of the numbers and names to avoid duplication.
