The cache is not at the posted coordinates
In order to determine the coordinates for the final cache location you will need to solve three Light Up logic puzzles. Here are the rules to solve a Light Up puzzle:
Stage 1
- For stage 1 ignore the numbers in the light boxes, you will use those later.
- Place light bulbs in white cells such that no two bulbs shine on each other, until the entire grid is lit up.
- A bulb sends rays of light horizontally and vertically, illuminating its entire row and column unless its light is blocked by a black cell.
- A black cell may have a number on it from 0 to 4, indicating how many bulbs must be placed adjacent to its four sides; for example, a cell with a 4 must have four bulbs around it, one on each side.
- A cell with a 0 cannot have a bulb next to any of its sides.
- An unnumbered black cell may have any number of light bulbs adjacent to it, or none.
- Bulbs placed diagonally adjacent to a numbered cell do not contribute to the bulb count.
Stage 2
- Add up the values of all of the light bulbs
- Enter that value as a keyword in the checker
- Repeat for each puzzle

Stage 3
- Use the three words given to determine the coordinates for the final.
- Go find the cache.
You can validate your puzzle final solution with certitude.
Note: When you find the cache container you must find the log and sign it. Finds without a signature on the logsheet will be deleted.
