📖 Story

Hengifoss is East Iceland's most dramatic waterfall, plunging 128 metres from a plateau into a gorge. But the waterfall shares the spotlight with the cliff face itself — alternating layers of black basalt and red clay stripe the rock like a geological barcode. The red layers are ancient soil horizons, formed when forests grew between successive lava flows millions of years ago. The trees rotted to clay preserved in stone. It's a waterfall and a time machine to prehistoric Iceland.
