One of the jankiest trails in the No Flow Zone. Has some really great rock rolls but also some particularly brutal (and frequent) climbs.

Cleared the trees. Downhill(ish) section is snow free, but some snow in the top half that you would have to push through.

      Attempted this trail twice, but both times ended up on "off the map trails". These trails were awesome rowdiness. Will try again soon to find the "correct" lines on this trail. I guess it's why they call it "Trial and Error"

      We hope you've been enjoying Trailforks!
