Geocache Description:

You will need a tape measure or ruler!

This cache is located near Cowcroft Trig Point, which was originally found in the old YSM series, and retains its original number of YSM 0339, and was found on 14-08-2011.

As these are survey pillars, you need to do a little easy surveying to calculate the cache location. At the trig point, and using your chosen measuring device. Measure in Centimetres  the width (horizontally) of the flat  face of the pillar across the dead centre of the S**** flush bracket number, look for the black measuring marks, and call this number AB. (Do not include the corner chamfers in this width)  From the top lip of the pillar, measure downwards 930 mm to find 2 letters. Where A=1, and Z=6 (dropping the leading digit), convert these letters to numbers and call them  C & D.

The cache can be found at  N51 42.B-(C+D)  A-D  B-D     W000 34.B+(D-C)  B-C  A-(D-C)

The nearest parking is, come in from Botley, at the end of Tylers Hill Road by the church.

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.
