In 18 years, geocaching has grown from a single container in the woods of Oregon to a global game with over 3 million active participants annually and more than 3 million geocaches. In the last year, Geocaching HQ Volunteer Reviewers published nearly 8,085 caches per week. Wow; thanks, Reviewers!
This growth means that almost anywhere in the world, you can find a geocache nearby. But it also means that geocache saturation is increasing. In some areas, it is becoming difficult to find a location to place a cache.
