Jökulsárgljúfur is a canyon in Iceland formed by the Jökulsá á Fjöllum river, known for its dramatic landscapes, including waterfalls, cliffs, and basalt formations. The canyon was shaped by a combination of glacial meltwater floods and volcanic activity, making it significant for studying geomorphology, glacial processes, and volcanic landscapes.
