Some rock movement and some washout from the recent storms but manageable.

No idea why this is rated a double-black diamond, the downs aren't bad at all but the climbs are steep. Still, there's harder climbs and descents...

 This trail is best ridden from opposite direction. Makes for a really challenging climb that is rideable but very difficult. Most will not be able to ride this unless an experienced technical climber

 I think it is more fun to ride trail 100 here, around--either direction--than this trail. I live right down below it and try to avoid the big hill as it is very eroded.
