For most, the evolution of the geocache container begins with the iconic metal ammo can. But in nearly two decades of geocaching, the geocache family tree has branched off into dozens of directions.

Each branch embodies the spirit of evolution. Geocaches now blend more and more into their natural environment. Say you place a cache on the outskirts of an estuary? There’s a bird geocache for that. Or perhaps you’re considering an urban cache on a park bench? There’s a magnetic Micro cache disguised as chewing gum for that.

There are hundreds of variations on geocache shapes, from whimsical (a small yard gnome in the woods) to devious (a fake security camera attached by magnets to the side of a building)!

Geocaches are not the only part of the geocaching equation to evolve.  Geocachers have developed keen “geo-senses” over the years. That piece of bark looks a little off, or something about that rock doesn’t seem quite right!

The most interesting geocache containers are often the ones you’ve never encountered before and likely will never see again. Keep your eyes and your mind open when you’re geocaching. If you’re stuck, geocache pages often include helpful hints. Previous logs and pictures can also offer clues to find the geocache.
