Land Owner
Very deserving of its black diamond rating. Lower Bitterbrush reminds me of desert riding in southern Utah, almost like a steeper version of UPS/LPS in Moab. Suffice it to say, there are many technical rock features, interspersed with brief patches of singletrack to catch your breath. Many of the rock features have multiple lines, so get creative

Hard trail. Turned around halfway up last time I rode it, which was a few months ago. I'll come back to conquer it this spring!

What a cool trail! Riding down is a lot more fun than riding up. Would not recommend without a fairly big travel bike and some confidence on granite and sandstone.
We hope you've been enjoying Trailforks!
