To find the cache, balance the
mobile to get the values needed to find the
coordinates.
Enter the numbers 1 through 9 in the blank weights so that
the mobile remains balanced. Each number is used exactly
once. Ignore the
weights of the horizontal bars and vertical
strings.
Once the mobile is complete and balances, substitute the weight
values for the corresponding letters in the coordinate
formula.

Correct the listed coordinates as
shown to find the cache:
N 39° 17.736 + BFE/1000, W 076° 54.096 – DJC/1000
