GAGB's YOSM Adventure Lab now live
Posted by: Griff Grof on 16th Aug 2019
Our new Adventure Lab is now live!
Ye Ole Survey Monuments (or YOSM for short) (GC45CC) was a travelling Virtual cache owned by outforthehunt. The cache moved around the country and you could be looking for a specific survey monument, pillar, surface block, rivet or bolt. The cache was archived by Groundspeak in 2017. At the time, it had 25,076 finds by 3,528 cachers.
The GAGB's brand new Adventure Lab takes you to the 10 most visited YOSM locations. If you complete all of the stages in person, then you will have travelled the length and breadth of Great Britain... a true adventure! Good Luck!
