Geocache Description:

A series of caches exposing the links between the art and science of espionage with the pursuit of geocaching.

Spies Like Us - Recruitment (GC1Y4GR) - ARCHIVED
Spies Like Us - The Dead Drop (GC20JBG) - ARCHIVED
Spies Like Us - Honeypot (GC1Y4K5)
Spies Like Us - Surveillance (GC21RXK)

It's hard to walk around these days without feeling like you're being watched. I'm sure there are many geocachers (including myself!) who have been approached by security staff after being observed surreptitiously. In the world of espionage the watchers may be people on the ground, computers intercepting electronic communications, or satellites up high looking down.

The first reconnaissance satellites (codename CORONA) were developed by the United States Government during the height of the Cold War to spy on the Soviet Union, specifically their weapons systems and radar mobilisations.

Satellite imagery has come a long way since the 60s and is now an everyday tool, similar to our favourite piece of formerly military only hardware.

Your goal for this cache is to use satellite imagery to locate the cache.
