I placed this cache when I placed Blue Blazes VI and Blue Blazes VII. It's not on the Blue Blazes trail, but you can get here from there.
I had intended this to be a completely different puzzle, but I couldn't quite get it to work how I wanted to. After two weeks, I decided I needed to do something different.
To find the cache, you need to calculate the location using the 3 given parking locations.
The cache is 5066 feet from Parking 1.
The cache is 5509 feet from Parking 2.
The cache is 4400 feet from Parking 3.
The checker will accept coordinates within a tolerance of 30 feet.
You can validate your puzzle solution with certitude.
