More on this later. My wife and I drove the little Jeep through Titus Canyon yesterday and were enthralled! Washboard the first ten miles or so from Beatty. After that, just a slow road with incredible views. Recommend good tires! I actually used 4wd some of the way, but a 2wd rig with good clearance would do okay.
I would not want to be in Titus Canyon in a flash flood!
