Do you find yourself without the ability to sythesize Ununtrium from the decay of a bunch of Ununpentium you happen to have lying around? Do you lack the bismuth-209 to cold-fuse with zinc-70? Do you lack the apparatus to detect simple alpha decay? Fret no longer; you can still find some Ununtrium (though please don't keep it)!
Go to the posted coordinates. There you will find a sign in front of the playground equipment. On the east-facing side of the sign are two numbers separated by a hyphen, we'll call them A and B, so the sign reads like this: "...blah blah blah A-B blah blah blah..."
We will call "U" the atomic number of Ununtrium.(It's on this page!)
The final coordinates for this cache are:
N 45° 04.((U - 1) * A / 2) + B
W 93° 26.((U + B) * 2) + A
Park hours are 6:00 AM to 11:00 PM
(6 and 11 are not the numbers you need from the sign)
