Here is a game that I am currently playing. You will have to advance to at least level 10 to solve this puzzle cache. More levels is a bonus ... I find this one can be very easy or very hard depending whether or not the little light bulb goes on.
Follow the link to the puzzle page and write down the keywords as you solve each level. These keywords are used to solve the coordinates. NOTE: The keyword will take you to the next level. IE Keyword 1 is obtained after solving level 1 and will take you to level 2.
Take the letters in each keyword and make each into a number as A=1, B=2, C=3, etc, then plug your answers into the formulas below. Pretty simple ...
The solution will be 39 AB.CDE North and 77 VW.XYZ West
A = Keyword 1 Letter 3 - Letter 4
B = Keyword 2 Letter 7
C = Keyword 9 Letter 1
D = Keyword 6 Letter 7
E = Keyword 3 Letter 5
V = Keyword 4 Letter 5
W = Keyword 5 Letter 5 - Letter 6 + Letter 2
X = Keyword 10 Letter 7 - Letter 1 + Letter 6
Y = Keyword 8 Letter 3 - Letter 4 + Letter 6
Z = Keyword 7 Letter 3 - Letter 6

And while you are in the area of the cache ... head south a bit and there is a pretty impressive beaver dam. Check out all the evidence of their work on the nearby standing and fallen trees. Pretty awesome really ...
