Cache is the bonus for Rathdrum Walk Lab Caches. Coordinates above are NOT where the cache is hidden. While the lab caches are a short walk and near each other, this bonus is up the mountain. There is parking and you can walk up the main road/trail to within 40 feet of the cache, but it's not near downtown. However, the view of the town is good from there.

By completing the lab caches, you will be able to get the pieces required to decode the cache. Cache is a short drive away from the lab caches. The bonus cache can be found at :
