This is a three-step multi-cache featuring high places in the
Otaniemi region. To go after this cache you must be very confident
with your climbing skills, as there is a definite risk of falling
and even of fatal injury. The first step does not involve climbing
but the in the last two steps you have to climb at least to a
height of 10 meters from the ground.
You should not go for this cache during daylight. During the day
there will be a lot of geomuggles around all of the steps. All of
the sites should be easy locate even in the dark. If you have
problems finding the correct locations, there is an additional hint
for each of them.
The first target is not in the given coordinates but can be seen
from there. The target is a metal pipe that is located in the
highest spot visible to the initial coordinates. To make sure you
don't see unrelated objects, think that you're looking from the
ground level. You will have to determine the pipe's length and
diameter (in centimeters). Doing this from the ground level is very
demanding but not totally impossible.
The coordinates of the second step can be calculated using the
dimensions from the first step using following formulas:
Let the caliber or the diameter of the inside of the pipe
(rounded to the nearest centimeter) be A.
Let the length of the pipe (rounded down to the nearest centimeter)
from the longest visible edge be B.
Both A and B can be factored into
two primes. They don't have a common divisor and neither has 7 as a
factor.
The latitude of the second step is N 60° 11.X
minutes, where
X = (A+B)*4
The longitude of the second step is E 024° 49.Y
minutes, where
Y = (B-A)*24
The second step is the easiest of the three and there you can
find the coordinates to find the final cache. The hint is hidden on
top of a construction.
The third and final step is the most demanding. The cache is
small to a regular size glass jar and is hidden behind some sort of
a ventilation duct. If you can use the rope here to secure you from
falling, that will be most advisable. It might be diffucult to rest
on the top, so signing the log will require some acrobatic
skills.
A bonus for added challenge: When you find the actual
container, you will notice that it is not as high as it could be.
After you have signed the log, feel free to return the cache to the
highest possible level. If you take it there, I'll take care of its
maintenance.
