Did you know that the Geological Society of America has Earthcache Discovery Awards? They sure do! The second level is Mica and is awarded to those that have found one hundred earthcaches. You can apply through their website for a nifty little badge you can add to your Profile. Time to learn about Earth!
CHALLENGE! Find 100 Earthcaches.
Below is an example of my completed requirements from my profile.

The cache is at the posted coordinates! You may find and sign the physical cache for this challenge before you qualify, but log it as a Note. Any found logs that do not qualify will be deleted. Difficulty is based on requirements and terrain is based on physical cache location.
Verify your requirements with the challenge checker courtesy of Project-GC.

Congratulations to LostinDenver on the FTF!
