The Betty Jean Prospect is a small mine out Quigley Gulch. There is mostly just remnants of an old structure and a couple of mine entrances.
To access this mine, you will need to travel about 2 miles down Quigley Gulch road. Once the road begins to turn to your right, you will need to park and walk into Deadman Gulch. The mine is up and to the left as you follow the trail. You need to do some bushwhacking to reach this mine.
