I figured the intersection of 11 and 13 to be a prime place for a
cache. Since 11 and 13 are both prime numbers. But when I started
walking around, I discovered that the area is just littered with
prime numbers. I suspect there is some kind of mathematical anomaly
at this site, but I have not been able to devise a theorem on
it.
In case you’re wondering, a prime number is a natural number
that is divisible only by 1 and itself. Examples are: 2 3 5 7 11 13
17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97. You can
find a list of primes under 20,000 at
http://www.math.utah.edu/~alfeld/math/p10000.html (although none of
the primes in this cache are over 10,000).
For the sake of this cache, letters and punctuation separate
numbers. For example 2-3-2011 is considered three separate
numbers.
At stage 1 you’ll find a prime number that I’ll call
“abcd”.
Find stage 2 at N 44 47.(cba-002) W 093 15.(cda-020).
At stage 2 you’ll find a blue object that says
“Attention” followed by a prime number that I’ll
call “ef”.
Find stage 3 at n44 46.(ffe+650) w93 15.(ef+056).
At stage 3 you’ll find two green objects. One of these
objects has a prime number, that I’ll call
“gh”.
Find stage 4 at n44 47.(ggh-113) w93 15.(ghg+203)
At stage 4 you’ll find a prime number in black lettering,
that I’ll call “pqrs”.
Find stage 5 at n44 47.(pqs-2) w93 14.(sqq+223)
At stage 5 you’ll find the physical cache.
The whole course covers a little over a mile. It is arranged in
something of a circuit that will bring you back near your car,
parked near stage 1. I suppose you could shave a couple of minutes
off by driving the course, but we can all use the exercise, right?
