More pictures, my Toyota buddies call this portion of the creek bed the bunny trail. I parked after the first mile or two & jumped in with one of them at the end of the bunny trail, I'm a little too inexperienced to be going through the big rocks without any protection in a jeep that hasn't seen its first payment:
Expirienced Jeepers know photos typically flatten out obstacles and inclines. But with the tires and people around to provide some scale in your pictures, them look like some good sized rocks in that bed.
It's not just a Jeep, it's an amusement park on wheels.
