As a throwback to the days of the 3D Stereogram image, you must find the missing decimals in the following images. Once found, put the decimals into the following coordinates:
N 45.09.'A'25, W 93.02.'B'84
where 'A' is the number from the first image, and 'B' is the number from the second.
The cache is a camo'd 4x4x6 lock-n-lock type container. Starts off with a special treat for only the completely famished. (nothing gross)
Terrain is tall grass/cat tails. You shouldn't have to get wet in order to accomplish this task, but do watch your step.
