There are probably 30+ more boulders in the area of Cascade Boulders. But they are to spread out to put in areas for them. The NWOR book has a map with many of them, or you can just wander until you find them. Lots of potential here for more good problems!
The rest of the boulders are scattered along all 3 gravel roads, so start looking. If you follow the access road to the east, you eventually hit a trail, (Herman Creek Trail?) Follow it a few hundred feet until you reach a large boulder on the side of the trail. If you look into the woods, you will see a large talus field. Lots of boulders, very little development so far. Have at it!
