Nagol
- A tall wooden tower built from local timber and vines, several stories high
- Flexible vine cords cut and measured to match each diver's height
Traditional towers are built to heights of 20-30m using lashed wooden poles.
Village men spend weeks building a tall tapering tower from cut timber, lashing the wooden platforms together with vines at increasing heights.
Each diver selects two vines, testing their length and flexibility to ensure they will stretch just enough to slow his fall without snapping.
The vines are carefully tied around the diver's ankles while he stands on a small platform built out from the tower at his chosen height.
The diver crosses his arms over his chest, leans forward off the platform, and dives headfirst toward the ground below.
The vines stretch taut and check the diver's fall just before his head or shoulders touch the earth, which has been softened and tilled beforehand.
Divers from higher platforms earn greater prestige within the village, with the practice traditionally tied to blessing the year's yam harvest.
