The final cache container is NOT at the listed coordinates, this puzzle must be solved first to discover those coordinates. This may be easier to solve while at a computer.
Here are the final coordinates: N 44 13.XXX W 124 04.XXX
Be careful on these narrow one lane roads, you never know what you might meet around that corner. Coordinates could be a little loose here with all the trees and mountains.
Here is the puzzle:
In mathematics, the absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign. Namely, |x| = x for a positive x, |x| = −x for a negative x (in which case −x is positive), and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.
So what does all this mean for this puzzle geocache? What you see is what you get, what you didn't see is what you didn't get!
The checksum for the correct number are 31.
