Geocache Description:


Powerful Chemical Conundrums

This series of progressively more complicated mystery caches is based in southern Tasmania. A feature of the series is that no waypoint is available for any of the caches. Each cache is located near an electrical distribution pole or tower ("Powerful"). To find the coordinates of the pole or tower you will need to solve puzzles based on chemistry ("Chemical Conundrums"). Each pole or tower has an identifying label attached to it. You will require this information to solve one or more puzzles to discover where the cache is relative to the pole or tower.

More explanatory information is given in the earlier members of the series (PCC 01 to PCC 10). It is recommended that at least some of these should be completed before attempting the more difficult final members (starting with PCC 11).

Special bonus: each of these final conundrums reveals information that can be used to locate a cache in the Wellington's Seldom Seen Sites series.

POWERFUL CHEMICAL CONUNDRUM 13 - Wellington Park 06

This mystery multi-stage cache is located in Wellington Park. The first cache is not at the listed coordinates. To find it you will need to solve a chemistry-based puzzle. The area is partly under tree cover and this will probably interfere with GPSR reception.

Part 1
The required transmission tower is at S 42° 53.x' and E 147° 16.y' where x and y are both three digit integers.

This puzzle involves aluminium that can be said to be the thirteenth element (selected because this is PCC 13).

  • x = (10a + b) * (10b + a)
    Where:
    • The atomic number of aluminium = 10a + b (a and b are single digit positive integers).
  • y = 5c
    Where:
    • c is the sum of the number of neutrons and the number of protons in an atom of the only naturally occurring radioactive isotope of aluminium (c is a two digit integer).
You can check your answers for this puzzle on GeoChecker.com.

Part 2
Proceed to the transmission tower at the specified location: it has a label "Transend ghiTjk" where g, h, i, j, k in "ghiTjk" is each a digit in the range 0-9.

The first cache in this multi-cache puzzle is located nearby. It is about m metres from the centre of the tower base and has a bearing of n degrees (from tower to cache).

  • m = (g + j) * 10
  • n = (100 * i) + (k - j) * 10
Parts 3...
This first cache contains information that leads to the second cache and so on until the final cache is found.

The Final Cache
The last cache in this sequence contains a log book and pen. There are no "swaps", instead there is information that will enable you to find the companion cache "Mossy Mystery 02" GC2Y4R3 a member of the Wellington's Seldom Seen Sites series.
