As an ex-navigator for the military I have determined my
position in many different ways. I usually used the stars, the
moon, and/or the sun. All my practice was intended to maintain
proficiency so that when we were flying over water or during times
when radio devices were turned off (during war), we would always
know where we were. I was lucky enough to come to the end of my
military career as the GPS was making my job unnecessary.
Today pilots don't need human navigators because of the
capabilities of the GPS. In that distant past when I was practicing
my craft, and not allowed to use radio signals, my pilots would
triangulate our position by means of VOR, TACAN and radio beacons.
Some of these could only tell you what direction you were from
them. Others could tell you direction and distance from them. When
only direction was available, the pilots would have to get
direction from two or more radio frequencies.
Your job, if you decide to accept it, is to determine the
position of this cache using only the direction from several
objects.
When you are at the cache you will see the a lightpole at
exactly 21 degrees magnetic.
You will also see a tree with a break in the bark at exactly 90
degrees magnetic.
And you will see an interesting rock formation at exactly 129
degrees magnetic. Can you find it?
