Went up to Long Lake thats in No, Cal. To day here are some pics. The stair case had 3' rocks and 4' holes that you needed to stay out of. You can see the size of the small rocks by looking at the Jeep ( it's my wifes jeep, the bronco II is mine)
I just seen this, The one with the bronco where everyone is standing around, the rocks are just below the bumper? well the bumper is 3' off the ground I did not think they were that big.
Long lake is in the High Lakes OHV park. It is east of Chico Ca. about 1 hour east of Paradise. If you have a good TOPO program you can find it. It is also open in the winter and the snow gets up to 15'. When I go up this winter I will post some pics. If you want to see some movies you can go to 4X4trailhunters and look for the high lakes movies. (most of the guys have jeeps)
