Warning: The series is set in a typical rural area. Roads can be narrow with limited parking opportunities next to caches. Safer parking may be up to 100m away. Traffic is usually intermittent but can be much greater during harvest time. Vehicles can vary from quad bikes through to large harvesters. Vigilance is required at all times, particularly with geokids.
The caches in the series are not located at the published coordinates.
It is envisaged that the set will be completed over a period of time but could be done in a day provided the geocacher has undertaken some preparation and has access to the internet during the day. There is good mobile phone coverage in the area for a range of wireless devices.
The caches are arranged in four groups:
- the starting point (The Octagon – Start)
- the outer group (The Octagon – Outer 1 through to The Octagon – Outer 8)
- the inner group (The Octagon - Inner 1 through to The Octagon – Inner 4)
- the final cache (The Octagon – Final).
The Octagon – Start must be completed before attempting any other cache. All caches in the outer group must be completed before any of the inner group. And, of course, all other caches must be completed before attempting The Octagon – Final.
Check Point
Before attempting this cache you must have completed The Octagon - Outer 3 (GC3V9VF)
Your Tasks
Four tasks need to be completed:
- Sign the log book for The Octagon - Outer 5 (GC3V9VK).
- In the front of the logbook you will find a value for " e= ". Record the value as you will need it for getting to The Octagon - Inner 1, The Octagon - Inner 2, The Octagon - Inner 3 and The Octagon - Inner 4
- In the front of the logbook you will also find a codeword which you will need after you have solved the puzzle below. It would be advisable to write the codeword on the data recording sheet.
- Complete the following puzzle.
