Ye Ole Survey Monuments (GC45CC) was a travelling geocache that is 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. As each location was a unique place multiple logs were allowed. This was true until it was archived by Groundspeak in 2017. However, the locations can still be visited and those visits logged on the Memorial Cache (see below). The interactive map at the bottom of the page and the downloads available in the resources section should help you find the nearest ones to you.
