Please park at (and only at) the provided waypoint. Yeah, it's up there. There's no defined path to the cache and you'll have to make your own trail. To say you'll be roughing it is an understatement! If you go efficiently and directly to your destination, it should be a little under a 3/4 mile round trip hike. Watch your footing and be mindful of the loose rocks, snakes, and other potential hazards that you may encounter at the top.
Let us reiterate: the last few hundred feet is a treacherous and dangerous trek to the top. Do not attempt unless you're comfortable navigating a giant boulder field along a steep slope!
The container you seek is an ammo can that is camouflaged with its surroundings. Common geosense will lead you to it easily; the difficulty rating is more of a factor of bushwhacking and navigation than anything else.
As always, have fun, be safe, and bring your camera. We'd love to see photos accompany your logs!
