Hello Sam D.
Let me see if I can help you with this one. You know the way to Bowen Ranch, so it should be pretty easy to give some landmarks to help you out.
When you are driving up Bowen Ranch Road, you will pass Coxey Truck Trail on your left. There is a street sign there, a sign for Oak Springs Ranch, and a BLM sign. Then you will come over a little hill and the road will curve sharply to the left, then the right. You will pass a private driveway there with a big gate and some rocks. Then you will climb through a couple of curves and come to two driveways on your left where some rocks are painted white. Both driveways go to the same place. The cattle guard is just past the driveways, so don't cross the cattle guard. (it is the only cattle guard on the road) Turn left on one of the driveways and drive just a little ways and you will see the signpost for Cascade Trail.
I hope that helps, and I look forward to seeing you.
