The cache is not at the listed coordinates, but is within 1 mile.
After helping runeshower build a puzzle that surprised us both with its apparent difficulty (since it's had so few solves), I decided to try my hand at something a little easier.
The first column of the puzzle grid stays in place. Imagine that the other columns are wheels on a cryptex that rotate around, and one combination of wheels will reveal 10 words.
The cache is hidden at N 3 _ ° _ _ . _ _ _ and W 1 _ _ ° _ _ . _ _ _ .
