When solving this puzzle, you should assume that the world (or at least the east bench of Salt Lake City) is flat.
To find the cache you will need to visit two locations. Both have plenty of parking within a couple of hundred feet.
When you locate the cache, take a deep breath and remember how it was hidden so you can put things back exactly as you found them.
Be sure to recap the container tightly.
If you enjoyed the geometric aspects of this hide, you should check out MOCKBA's "Suspended between benchmarks" (GCGZP1) and enjoy a trip into the third dimension.
Congratulations to himilecyclist for being first to find.
