Easiest jump line at Thunder Mountain, no gaps and everything is rollable. A great trail to build confidence on or to take a break from the more intense riding.

Most of this trail is skiable in the winter, IF snow conditions are firm / fast. You'll have to push for some of it, and snowboarders will find this to be a real chore in spots ... but you can have a good time on this if conditions are right. You might want to cut some of the switchbacks off by skiing through the trees to carry speed / momentum. On snow the two best parts of this trail is the series of 3 tight berms near the beginning, and the final jump line near the end.
