This trail prevents the Poison Spider Mesa trail from being an out-and-back, and has a fierce reputation as a man-eater. It is hard to find, and the one section where people died is clearly marked - although most people's common sense will be screaming out warnings without needing a sign to tell you to dismount. The spot marked as the falling point for the fatalities is a perfect storm of a high rock obstacle ready to catch chain rings or bash guards, a protruding rock leaning into the trail at rider height, and exposure to a short, steeply pitched slope falling off hundreds of feet to the river.
The rest of the trail is technically challenging and not especially death-defying. There are some gonzo moments, though with rock ledges and limited exposure, as well as some dips that will exert g-forces on the fast moving rider.
At the bottom it is just a short ride up the road back to the parking lot for Poison Spider Mesa trail.
