THIS CACHE IS NOT AT THE ABOVE COORDINATES: On the morning of
January 29th, 2009, Carson City was struck by 3 earthquakes. Most
of you never even knew about it as they were too small to be felt.
Regardless of that, they still happened. Once they were verified by
a seismologist, I plotted the epicenters on a topo map. These 3
epicenters were all in the SE part of Carson City.
By connecting the 3 epicenters, you can form a scalene triangle, so
instead of hiding a cache at all 3 locations(one of which was on
prison property), I decided to hide the cache at the Centroid of
the Triangle. Here are the coordinates of the 3 epicenters, and
from there you will be able to calculate the Centroid. Earthquake
#A was a 1.6 magnitude, and the weakest. It was located at N 39
06.120 W 119 44.040. Earthquake #B was 1.8 magnitude and it was
located at N 39 06.660 W 119 44.220. Earthquake #C was the
strongest at 2.1 magnitude and it was located at N 39 06.540 W 119
44.040. The difficulty rating is based on whether or not you have a
map with coordinates to be able to plot the 3 epicenters. A topo
map on a computer is the easiest way to do all the plotting. To
start finding the Centroid, you first need to measure the length of
each side of the Triangle. Since a 1 foot discrepancy from my
measurements compared to somebody else can make a big difference,
here is some assistance to get started. You will only need to be
within 100ft as I'll give you the last 2 digits of each
measurement. From Quake A to Quake B, it is _ _ 00ft. From Quake B
to Quake C, it is _ _ 20ft. From Quake C to Quake A, it is _ _
50ft. From there, you need to figure out the rest. Also, the ammo
can being used for this hide was won by me, at the dinner for the
GBES 2008 Navigational Rally (Yes, I am finally using it). In it, I
have placed the movie "10.5 Apocalypse"(an earthquake movie, of
course), tape measure, glow sticks, water proof match container,
Are You Smarter Than A 5th Grader card game, and a mini set of
screw drivers.
