Dimple Hill Summit
If you hit it at the right time of year you'll be greeted to large bushes of the invasive Himalayan Blackberries. After relaxing for a bit continue on down the backside of Dimple hill to an intersection of forest service roads. Follow the one down the hill to the right. You'll follow it for a ways mostly descending. Once you start slightly climbing you'll know you're close to the turn off for Horse Trail.
