Geography
The waterfall is surrounded by layers of basaltic strata. In between the basaltic layers are thin layers of red clay. Geologists have also discovered fossilised trees within the layers, evidential of much warmer periods during the tertiary period. Further down the waterfall’s river, Hengifossá, is another, smaller waterfall known as Litlanesfoss, which hikers should pass on their way from the parking lot up to Hengifoss. The river eventually runs into the famous Lake Lagarfljót, home to the mythological sea wyrm Lagarfljótsormur.
