The good news is that the majority of the hike to this cache is along a hard-surface hike/bike trail. The bad news is that this is a 3 to 4-mile hike from the southern trailhead and the last 300-feet involves bushwacking up a steep ridgeline. But the good news is that the container is a small, black bison zip-tied to a tree. 
And since its a bison you will need to bring your own pencil/pen.
The Difficulty rating of 3 reflects the challenge in finding a nano in the woods (or should I say "in the cedar grove"). The Terrain rating of 3 reflects the realitively long hike, rocky & steep terrain approaching the CZ and the abundance of thorns, PI and wild critters.
There are toilets and drinking water at the trailhead...
