There is a trail but it has a lot of small blow down across it.
The cache is hidden where you will have no problem grabbing some birds. Bring your lunch or snacks and plenty of water and enjoy the view.
You are searching for a small snap and lock container. Shouldn't have any problems with muggles here.
More info have a listen here Horse Rock Ridge by John Cooney Thanks CFM
The following geocache by Cathy and Tom is what brought me to this general area in January 2003.
Shotgun Creek
Make sure to visit Odder's geocache The Mane Cave further up the trail for great views of Mt. Jefferson and the Three Sisters
