System and refers to a system of 24
satellites that orbit Earth and send
signals to receivers.
5. The first geocache was hidden on May
3, 2000 when Dave Ulmer hid a cache in
the woods near Beaver Creek, Oregon.
He shared the coordinates online and
the hunt began.
There are currently 2,107,846 active
geocaches and over 5 million
geocachers worldwide.

14. Difficulty

cache and is trated in two categories..D
/T (Difficulty and Terrain)
Both are rated using a five-point scale
with one star being the easiest and 5
stars the most difficult.
