This cache IS at the posted coordinates, but you must meet the challenge qualifications in order to log a find.
CHALLENGE:
A call or summons to engage in a contest of skill, strength, or competition.
The cache IS located at the posted coordinates. To be able to claim a find on this cache, you will need to:
Find at least 100 caches in the state of Washington with at least 100 favorite points each. Everyone likes to find great caches. This challenge is to encourage people to go find the best caches in Washington state. People give favorite points for any number of reasons - and this challenge is meant to recognize all of them - whether they are particularly clever or simply take you to a beautiful view or location.
Past finds count as long as they have at least 100 favorite points each. Archived and disabled caches count as long as they meet that guideline.
But, I must be able to confirm it. Attached is a link to Project GC if you would like to use it.

Be careful. Be safe. It's steep getting to the cache. Be considerate of the new landscaping and plants. Do your best to leave no trace. And, don't forget to sign it. A marker is already provided.
Re-hide the cache in the way that you found it. Enjoy the view of Johnson Creek from this angle before returning to your cache mobile. It's a surprisingly pretty area.
Congratulations to Hwy88 for the first to find the cache and to sign it! 
There is plenty of parking for several vehicles just off of Whitefeather Way. It's just less than .3 from GZ along the ODT trail but at least you don't have to play frogger to get to the starting point. Do note the terrain before attempting to find the cache. - It can be hazardous if you are not prepared.
