A Circular Challenge Kick-Off Event Event Cache

Geocachers like numbers.
 

And what better way to improve your numbers than by trying to qualify for Challenge caches.  They might encourage you to visit new states, find caches in more counties, or find caches in other countries.  You might search for caches with different D/T ratings, find caches placed back when geocaching was new, find more caches of a specific type or caches with a specific attribute.  We have placed 30 geocaches for you to find, grouped into 10 different categories.  Nine of the categories are rated bronze, silver, or gold, depending on the qualification value.  The final category contains a potpourri of challenges based on other criteria.
 

Notice: This event is NOT on the Barry M. Goldwater Range, but the challenge caches are.  A free permit [here] is required to enter the BMGR.  You need to check in online before entering the range, and please, drive only on marked roads.
 

These 30 geocaches might also be considered a "GeoArt" as they do form a shape out in the desert.  Be prepared for desert hiking as you CANNOT DRIVE to most of these caches.  The road to and from the cache area is not too bad but AWD and some clearance is recommended. 
 

If you plan to go after these challenge caches, remember that you must have a range permit and you must check into the range, online, before you go.  Also note that these are desert conditions, so bring plenty of water, sun protection, and don't pet the snakes.

See you there.
