Dettifoss

Dettifoss is an Icelandic waterfall where glacial river discharge crosses basalt terrain and drops into a stark canyon cut through volcanic rock.

Basalt canyon setting

The waterfall is shaped by the interaction of high-energy river flow and volcanic bedrock. Canyon walls expose the hard rock framework of the landscape.

Glacial river power

Glacially sourced discharge gives the falls strong flow, sediment load, and spray. Plunge-pool erosion helps maintain the abrupt river drop.

Rock

Basalt canyon

Volcanic bedrock frames the waterfall.

Water

Glacial river

Cold highland runoff drives powerful discharge.

Terrain

Icelandic plateau

The falls belong to a volcanic highland drainage system.
