As a climb, it is extreme. Going downhill, it's challenging. This was an old fire/access road that was not built with our modern understanding of erosion and water control and is literally used as a living example of how not to build trails.

 Funnest downhill yet; be prepped for the usual suspects: Major erosion (major ruts or slumping, large boulders and roots exposed due to erosion)

 Significant erosion ruts after recent rains. Trail work done about a year ago is starting to show it's age, back to being pretty sketch.
