To hunt the clues for this cache you must be a certified SCUBA Diver. By seeking this cache, you are taking full responsibility for your own safety.
The cache is located at 'Miracle Waters' Inland Dive Site, South Africa (the above coordinates is not the final location of the cache). The cache container with log book is hidden on dry land.
There is an entrance fee payable for divers and non-divers visiting the dive site. Scuba gear can be rented at the facility and there is a compressor room for your air fills.
You will need to dive the bus wreck at about 17 meters to solve the puzzle leading you to the final cache.
The recommended entry point into the water closest to the bus wreck can be viewed in the waypoints listing.
Also consult the map of the quarry that is viewable on a display board close to the given entry point waypoint.
Find your way to the buoy indicating the location of the bus wreck. Once you dropped onto the bus using the buoy line, gather the answers to the following questions (I recommend you take along a slate with the questions and a pencil to write down your answers):
(A)
How many tyres are still intact on the bus? Take this number and add 3 to it to get (A).
(B)
Does the bus still have its steering wheel? If yes then (B) = 6, if no then (B) = 3
(X)
Count the number of window openings on the "port-side" of the bus (this is also the side where passengers would have entered the bus), excluding door windows. Multiply this number by six, take the first digit of your answer and divide that by two to get (X).
(YZ)
Count the number of passenger chairs (units) still intact in the bus. Multiply this number by 8 and add the value of (A) to get (YZ).
The coordinates of the cache (on dry land) are at:
S25 40.ABB E 027 45.XYZ
There are quite a few wrecks to dive at this site.. make a day of it and enjoy!
