Geocache Description:

Formerly known as "Sussex Trig Points #15 - Devils Dyke" until 14/4/24

A series based on trig points in Sussex. You can also log your trig find at where you will find a plethora of information and statistics about trigs.

This pillar is also a YOSM (Ye Olde Survey Monument) which can be logged at GC45CC

Devil's Dyke is an historic beauty spot on the South Downs Way, named after the huge dry valley that carves its way through ridges of rolling chalk grassland.

Legend has it that the Devil dug the valley to drown the parishioners of the Weald. Scientists, on the other hand, believe the largest "dry" valley in Britain was formed in the last ice age.

Unless you are a National Trust member you will have to pay £2 for parking

To find the cache visit the trig at the published coordinates and note the number on the flush bracket.


The cache is hidden at:

N 50.53.(B+1)(2*C)(3*D) W 000 12.(A-1)(2*A)(A)

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.

The cache is about 700 metres away and you will have to walk!
