It's a K rail that was setup to go over. Skip made a plaque for the first 10 people over it. It's on the main trail off to the side right before you get to the bottom.
Yeah it definitely requires skids and a drive shaft that's above you lower links. I got over it first shot and put a nice dent in my center skid, Matt broke his rear drive shaft going over it but made it. Fun but I probably won't do it again in the black jeep. Maybe I'll give it a whirl in the red xj if it ever moves again.
