Death Canyon

You thank that root now.

A Death Canyon is a place that people slip into after an accident of some kind. The only things that save them are sudden amazing reflexes and grabbing an Ex Machina of a root that connects to no known tree sticking out of the canyon wall. Without any way of getting back up, they helplessly gaze down into what awaits them below: a rocky grave often accompanied by a nearby creek. Should they lose their grip or the root snap, they will die soon after.
