| Challenge Cache | Geocaching Term/Cache Type A Challenge Cache is a Mystery/Puzzle cache that can only be logged after certain requirements are fulfilled by the seeker. One of the most popular is the DeLorme Challenge which requires the finder to first find at least one cache in every square on a particular state's DeLorme Gazetteer Map. Other challenges include the All County Challenge (at least one cache in each county of a state) and the Well-Rounded Geocacher Challenge. The final coordinates for a challenge cache are normally emailed out by the cache owner once the requirements are fulfilled. Often the requirements are checked through a shared bookmark list created by the seeker. |
