Dictum is rockier and steeper than union springs. Once you are in there it would be very hard to turn around. I would be afraid of flipping a hack. Think of it more like single track than a road. Let me see if I can dig up some pictures.
edit pictures: If you look at the album, only the last couple are from the ledges on dictum ridge. The rest are from rough run and another road I forget the name of.
