Geocache Description:


**This geocache is at the posted coordinates, but to log it online as found you also need to complete the following challenge**

Your challenge is to find at least 30 combinations of terrain and type. Worded another way, can you fill at least 30 squares of the grid made with terrain and type. Qualifying finds can be hidden any date, be found any date, any location, any size, and be any difficulty. Since lab caches and benchmarks do not count for this challenge, here are the types you have to work with: traditional, multi, unknown, event, earth, letterbox, whereigo, virtual, webcam, CITO, mega event, giga event, GPS maze, HQ, Project APE cache, community celbration event, Block party, HQ community celebration event, and locationless.

I qualify and you can see if you do too using this checker:
