The cool thing about this trail is that it's a one shot descent from some really great camping spots. The first 1.8 miles are double track - nothing memorable. Once the single track starts, it's super fun! All obstacles are rollable. Definitely not a black. If you want something a little more rowdy, descend cable trail and connect to this. Happy trails

"Climb Difficulty" is black diamond when starting up on the west end, over 10% grade plus rock drops to roll up, then blue difficulty for the remaining 80% of the trail. Much more fun to ride down. (Have ridden it in both directions)

I really liked this downhill. There are certainly a few rock features which challenge its blue rating.

This trail is a blast to ride if you go downhill instead of climbing

This trail was VERY rocky. Lots of loose sharp rocks ranging from small gravel to softball size in the trail. There were multiple areas of the trail that were covered with these loose rocks making those particular areas much more difficult to navigate. I don't know that the rating needs to be moved to black diamond, but there are definite areas of more difficult obstacles than most intermediate trails I have ridden before.

One of the better trails in the area in terms of descending fun. First bit starts off mild and then gets swoopy & fast with some tech sprinkled in for good measure.

It's a bit of a mess. Patches of packed icy snow and uncovered tacky, wet, muddy trail.
