Stuðlagil

Stuðlagil Canyon (Icelandic pronunciation: [ˈstʏðlaˌcɪːl̥], also transliterated as Studlagil) is a basalt column canyon located in the Jökuldalur valley in East Iceland. Known for its towering hexagonal basalt formations and vivid turquoise river, the canyon gained international attention after the flow of the Jökulsá á Dal (Jökla) River was reduced due to the Kárahnjúkar Hydropower Plant project. Though the canyon was physically revealed between 2006 and 2009, it remained largely unknown until its popularization by Icelandic photographer and travel writer in 2016.
