TESL OG (RYUO AMTE) STEL OG! Mystery Cache

This cache is NOT located at the posted cache coordinates. However, the posted coordinates are a good place to enter the Sanford Natural Area on the MSU Campus.

To find the cache within the Sanford Natural Area, you will need to solve the puzzle below:

Once you have the squares all filled, you will need to take the letters in the 20 gray squares, convert them to numbers (A=1, B=2 ... Z=26) and sum them.

X = sum of the gray squares

The cache can then be found at:

N 42° 43.NNN
W 084° 28.WWW

where NNN = 834 - X and WWW = 228 - X

The cache is a clear snap lock container hidden in a typical way.

Congrats to Pianodan on being First to Find!
