Geocache Description:


Come and join me at the highest event in Bedfordshire to celebrate the 2nd anniversary of the Ye Olde Survey Monuments (YOSM) series. The triangulation pillar on Dunstable Downs has been placed at a height of 244 metres where there is a cache YOSM #0069 Dunstable Down, but the event will take place a few metres lower at the nearby View Café within The Chiltern Gateway Centre. The car park is free to National Trust members but it’s £3.50 for a day ticket for non-members. Bring along trackables and other geocaching items to exchange. There will be some artwork available to add to your Geocaching profile from the YOSM website after the event, please see link below.





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.
