Was just out there a few weeks ago. The road to the camp ground is in good shape. The first crossing from there that used to be really deep has been filled with gravel, should be no problem at all. The second river crossing was worse (although pretty much anything would be in comparison to the first), but not too really not too bad. The Omaha Freeway is in fine shape (RR ballast), but the canyon floor is the sandiest I've ever seen it. I got the truck stuck a few times in 2WD, but no issues with 4WD. Basin Rd is ok, but looks like it got torn up a bit more from the storms this past winter, and could use a good grading. I took my '87 Honda Accord (before I had the truck) out to Basin down Basin Rd, which was passable, but very slow going. Some extra clearance for the large rocks is very handy to have.

Hope that helps a little,
