In this exercise you are looking for a number of strangely named navigation waypoints.
The waypoints are:
KAURI
LOSGA
TOMAS
KINGS
If you formed a quadrilateral around these four points, the cache would be located somewhere inside it.
There is nothing physical at these points, but regardless they are quite important.
While as always google is your friend, and should lead you to some of the waypoints, it may not lead you directly to the document you require. A puzzle hint has been included.
When you locate these points you will use their coordinates to determine the location of the cache.
The coordinates of the waypoints, when found, will be in the format degrees, minutes, seconds and decimal seconds, with the South coordinate having 10 digits, and the East coordinate having 11 digits.
There is no need to convert these coordinates.
The following equations are in the format of: Waypoint Name, S or E (for south or east coordinate), a number (which digit of that coordinate to use)
The cache is located at:
S36 5A.BCD E174 5E.FGH
Where:
A = TOMAS, S, 4
B = KAURI, E, 6
C = LOSGA, E, 7
D = TOMAS, E, 7
E = KINGS, E, 6
F = KAURI, S, 3
G = LOSGA, S, 6
H = KINGS, S, 6
Please note that the cache is only accessible 8am to 6pm in winter, and 8am to 8pm in summer.
WARNING: The final location of this cache is in a cemetary. The likely place you will park is very sad, please take a moment to reflect. The cache itself is placed well away from any grave sites and not visible from any. Use discretion, and if there are any mourners around, perhaps come back another day.
