This cache is part of the Pokémon Master series. Final cache: https://www.geocaching.com/geocache/GCAXVD3.
On your journey to become a Pokémon Master, you must first know about the Pokémon in the world. This geocache will help with that. In this geocache, there will be an image of an unknown Pokémon. You must identify it. Once you have done that, record its Pokédex number, as it will be needed to find the final geocache.
The geocache is hidden along the Sterling Justice trail, which connects Cusick Creek with Gibson Jack. It's about an 11-mile hike one way. Parking one car at each trailhead is a good way to tackle it. The trail isn't very steep, just long. It is shaded in some spots but mostly out in the sun. Bring ample supplies.

You are looking for a black large container hidden inside a hollow but alive Juniper tree. Just a log, so BYOP!
