Tindfjallajökull
Tindfjallajökull (Icelandic pronunciation: [ˈtʰɪntˌfjatlaˌjœːkʏtl̥] ⓘ) is a stratovolcano in the south of Iceland.[1] It has erupted rocks of basaltic to rhyolitic composition, and a 5-km-wide caldera was formed during the eruption of the 54,000-year-old Thórsmörk Ignimbrite. It is capped by a glacier of 19 km².[2] Its highest peak is Ýmir [ˈiːmɪr̥] (1462m),[2][3] which takes its name from the giant Ýmir of Norse mythology. The most recent eruption was at an unknown time in the Holocene.[1]
The name means "Tindfjöll glacier". Tindfjöll ([ˈtʰɪntˌfjœtl̥], "peak mountains") is a ridge that extends to the south of the glacier.
The rivers that flow from the glacier are Hvítmaga [ˈkʰvitˌmaːɣa] to the north-east, Gilsá [ˈcɪlsˌauː] to the south, Þórólfsá [ˈθouːroul(f)sˌauː] to the south-west, Valá [ˈvaːlˌauː] to the north-west and Blesá [ˈplɛːsˌauː] to the north. Hvítmaga, Gilsá and Þórólfsá drain into Markarfljót while Valá and Blesá drain into Eystri Rangá [ˈeistrɪ ˈrauŋkˌauː].
