Go out and find the first waypoint-clue. In this example, waypoint-clue A was found first. Waypoint-clue A has the following values: 2, 5, 8, 2, 5. Write them going down in column A |
Waypoint-clue C was found next: 3, 6, 9, 3, 6 |
Finally, waypoint-clue D was found: 4, 7, 1, 4, 7 |
You don't need to
calculate the missing CRC in B-2, so you can cross it off (If you skipped waypoint-clue A, cross off A-1 & A-5. If you skipped C, cross off C-3. If you skipped D, cross off D-4.) |
To calculate the missing
values for B-1, B-3 & B-4, you use the calculate missing
values worksheet (Or A-2, A-3 & A-4 for A; C-1, C-2, C-4 & C-5 for C, D-1; or D-2, D-3 & D5 for D.) |
To make things easier, circle the waypoint dropped line, and cross off the skip if dropped boxes line |
Now follow the directions in the circled box for each row. In this case, starting with row 1, fill in the values for the first 3 columns. After the "Waypoint Dropped B:", it says "A#" above the first column of boxes. The # is the row you are working on, Row 1 first in this case. So take the value that was found for A-1: "2". Write this in the first box. Next is C#, so C-1 has "3", write that in the second box. Finally D#, D-1 is "4", write that in the third box |
Filling in the rest of the values from the found values: A-3, C-3 & D-3; A-4, C-4 & D-4 and A-5, C-5 & D-5 |
Now we are ready to calculate the missing blocks. We start by following the next direction in the circled line: A# xor C#. Doing Row-1, that is A-1 xor C-1. A-1 is "2", C-1 is "3". To do 2 xor 3, use the 16x16 XOR look-up matrix. We matched 2 with 3 on the matrix: 2 xor 3 is "1" |
Write the "1" on the forth box for Row-1 |
And the final step for
Row-1 is "... xor D# = B#". Take the value we just found, "1"
then xor it with the value from D# (D-1): 1 xor 4 That gives 5. |
Write the 5 in the last box for Row-1 |
And that gives us the answer for the missing value for B-1: "5" |
Jumping ahead to having calculated the other 3 rows |
Taking the rest of the calculated values, and putting them on the found worksheet |
Now put the values on the coordinates worksheet. Start with the first value, from B-1 "5" (for the coordinates, we skip the bolded CRC boxes) |
Continuing with the rest
of the coordinates, we have the GPS location of the
treasure/log cache N 053° 45.678 W 012° 53.467 as an example. This example winds up being in the Atlantic Ocean, on the coastal shelf off Ireland. :) |
Now it is time to do the proof. Start by circling the waypoint-dropped line for the waypoint-clue you skipped - B in this example |
Transfer the CRC values to the proof sheet. Starting with the value from A-1 "2" in the first box |
(If you skipped
waypoint-clue A, you skip the first box - you can cross it off
in that case.) Fill in the rest of the CRC values, C-3 "9", D-4 "4" and A-5 "5" |
Now to the calculations. First is A1 xor C3: 4 xor 5 = "11" - write 11 in the first box |
Take the "11" and "... xor D4", D-4 is "4": 11 xor 4 = "15" - write that in the second box |
And finally, take "15" and "... xor A5", A-5 is "5": 15 xor 5 = "10" - write that in the third box |
That is the proof for this example. That would be the number you can email to us to prove which waypoint-clue you skipped. |
