This cache is on Arizona State Trust Land. Geocachers must purchase an annual recreation permit available on the Arizona State Land Department website. Long sleeves are highly recommended.
It's another challenge - some people love them, other people hate them. The cache is located at the posted coordinates but there is a special logging requirement. You’re welcome to sign it (bring your own pencil!) and post a note at any time, but you cannot claim a find unless you qualify. The D/T is based on the challenge. The hide is a preform container.
They tell me that it is 24,901 miles (40,075 km) around the earth at the equator, but once is not enough. You must have done the equivalent at least five times.
The Challenge 
To qualify, the total distance between all your found caches (in the order they were logged) must exceed 124,505 miles. Adventure lab stops are excluded.
Note: The checker distance is calculated in Kilometers - 200,375 Kilometers is required. If a non Premium member uses the checker, all premium caches will be excluded from the calculation because of license issues.
Use the checker to confirm your qualifications. You're welcome to include the output from the Project-GC Checker in your log entry but it is not required.
Finds that do not qualify will be deleted without warning.
