Register in good condition, a new canister is needed. On the guide's 3.4 mile section of road just W of Inca, there's a significant wash out that has a 300 foot long, deep sand detour. This could trap 2WD, as my 4WD was beating hard to get through. Continuing down the road, 4WDs should have no problems other than slowing for occasional ruts. However, around pole 48-4 4WDs with HIGH clearance are a must.
Camping is fair here except for the strange noises emitted by the power lines.
The route goes well, but I'd rate it a class two instead of one. I didn't do the S summit. The round trip took me 4.5 hours. Register and canister in good condition. Back out at Midland Road, I took the excellent Blythe-Rice road N to SH 62, then the Ironage Road shortcut at Dale Dry Lake to Amboy road and Sheephole pass.
