|Ye Ole Survey Monuments (GC45CC) is a travelling geocache that is owned by outforthehunt. The cache moves around the country and you could be looking for a specific survey monument, pillar, surface block, rivet or bolt. Unlike conventional geocaches, with this cache you need to record the co-ordinates you find and make a note of them on your log. You can also add pictures and any other details you want. 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.||

|Difficulty and Terrain ratings||We are collecting Difficulty and Terrain ratings for the individual monuments. To participate just include your ratings in your log, e.g. D/T 1/2. An example log can be found here. If you would like to give ratings for the monuments that you have already logged please email us and we will send you a personalised spreadsheet to complete.
|Missing YSM numbers||The accuracy of some of the charts and maps has been reduced because the monument visited could not be identified. Please include the YSMxxx number in your future logs and, if possible, edit previous logs if they do not have the YSMxxx number.
There are logs where the YSM number could not be determined. A list of these can be downloaded here in .csv or Excel format.
|'Statpics' showing your finds and ranking are now available. See the Utilities page for details.|
