The cache is at the posted coordinates, but you must meet the challenge qualifications in order to log a find.
Anybody who has found 2500 caches or more qualifies for this challenge.
Of course all previous found caches count, including archived caches.
You don't have to do anything special to show you qualify because your stats show how many caches you have found. You are welcome to sign the physical log and post a note on the cache page if you have not qualified yet.
