6/14/14: New cache container, location, and coordinates. The puzzle is still the same, but the math has been modified. Please be delicate with the cache camouflage.
This is a Codeword type puzzle. Each number in the crossword grid stands for a letter of the alphabet. Your job is to crack the code. Once you've figured out the letter that matches a certain number, place that letter in every square containing that number, as well as in the chart below the grid. Every letter will be used exactly once in the bottom grid.
Cache is located at 47 32. @ $ &, 122 13. ! % #
@ = K / P
$ = F / C
& = J - N
! = S - I
% = R - 8
# = L - 2
