In order to qualify for this challenge, you will need to have found at least 10 caches with the "Field Puzzle" attribute. This is a gadget cache, which is one type of field puzzle. You may sign the cache even if you do not meet the challenge, and post the find as a note until you do qualify for the challenge.
When the "Field Puzzle" attribute is used, you should be able to solve the puzzle of how to get to the log while on site A field puzzle very well might be at the published coords or have a puzzle to find the actual coords. Examples include needing to look around at items then determine the padlock combo to access the cache, or a gadget cache where you have to slide pieces or unlock locks in the right order to access it. The coords can also be mystery (correct coords are a mystery until you solve the puzzle).
This cache is on Arizona State Trust Land. Geocachers must obtain a recreation permit available on the Arizona State Land Department's website in order to geocache here. https://land.az.gov/natural-resources/recreational-permits.
This container is a well designed gadget cache that I received as a gift after finding https://coord.info/GC9J9BG and told a friend about this cool container. The gadget cache should be opened with gentle manipulation. No force or tools are needed.
