John O'Callaghan Park in Riverstown is a small park containing a riverside loop walk and a play area for young children. There is limited parking at the entrance to the park, but plenty more in the housing estate across the road. All of the action around this cache takes place inside the park. It can get very waterlogged and muddy after heavy rain, so wellies may be required - be prepared!
To find this cache you will have to walk along the main path through the park from the starting coordinates to the gate at the far end. Look for the twelve pictured items and record the order in which they are found along the path. An easy calculation will reveal the final cache coordinates.
There are one or two other paths in the park so it is very important that you are on the path marked on the following route map:
Some of the items featured in the photos are not unique, so you may need to look at two or more things in the picture to be sure that you have a match. All of the individual pictures are in the gallery - you can zoom in on them there if needed.
This is what you are looking for:
To calculate the final cache coordinates:
Each picture contains a number. When the pictures are ordered into ABCDEFGHJKLM then each of those letters will have the associated number. The letter 'I' is not used at all, so J will be the number in the picture of the 9th item along the path. The cache is located at:
N 51 55.(G-A)(B+H-1)(K+E-2), W 8 23.(J-C)(L+F+2)(D+M-2)
The two three-digit numbers just calculated should sum to 1276.
NOTE: Feb 2018: The lifebuoy in the picture has gone missing (for now). Look closely where the two rivers meet to become one.
The GPS may be flakey at GZ so don't let it lead you into difficult terrain, (the cache is not hidden in the woods). If in doubt, create a waypoint using the final coordinates and look at it in satellite view.
The cache is a small Tupperware box. Lots of people visit the park, so please be discrete when retrieving the cache and post a DNF if you can't find it.
If you rock up without a printout of the pictures then the cache is still doable but will be somewhat awkward. A pencil and paper will be helpful. Waypointing the items as they are found may also be helpful.
Congrats to Greeenbug for the hard earned FTF!! Thanks for your patience with our dubious co-ordinates (which I hasten to add have since been fixed!) :)
