Every pillar is a trig but not every trig is a pillar.
Something a bit different for you this time. A number of the passive stations installed by the OS, in particular the FBM auxilaries, used a survey marker from Berntsen. This looks like a silver disk. The trig mark / datum point is located under the lid and is typically a 5cm domed disc. However, a simpler, centre punched rod has sometimes been used.
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 www.yosm.org.uk
so we can keep track of the numbers and names to avoid duplication.
