Listen. Pick a ridge with the same slope wolves use. Drag a long, thin string from a low ridge to the pass, tied to a dead tree. Behind the tree, set a camouflaged pit: a shallow hole, lined with bark, that covers the string. When the wolf crosses, it pulls the string, snapping a lightweight but sturdy net that covers the pit entrance. The net falls silently, the pit stays hidden by leaves. No map needed—just watch the wolf's path and the slope. Stay quiet.
