An aerial view looking east down the Snæfellsnes Peninsula shows the Bláfeldarhraun lava flow in the foreground. The cone that produced it is part of the Helgrindur (Lýsuskarð) volcanic system, which consists of small scoria cones and vents along a WNW-ESE trend across the central Snæfellsnes Peninsula. · 사진: Photo by Oddur Sigurdsson, 1983 (Icelandic National Energy Authority). · Wikimedia Commons

지질학적 요약

Helgrindur (also known as Lysuhóll or Lysukard) is one of Iceland's smallest volcanic systems. It consists of a chain of small alkali olivine basaltic cinder cones and vents along a WNW-ESE line cutting across the central Snaefellsnes Peninsula in western Iceland. The slightly arcuate line of Quaternary vents extends to the northern coast of the peninsula. Helgrindur is the central of three volcanic systems occupying the peninsula. The latest eruption is undated, but the system has been active during the Holocene.

영어 요약

Helgrindur is a volcanic mountain range or massif in the middle of the Snæfellsnes peninsula that provides a backdrop to the port of Grundarfjörður. The volcano can be regarded as potentially active, with a risk of lava flows and much more rarely explosive tephra eruptions. The range with its prominent peaks, of Tröllkerling at 891 m (2,923 ft) in its south-east, Böðvarskúla at 988 m (3,241 ft) and Kaldnasaborgir (Kaldnasi) in its north-west at 986 m (3,235 ft) is popular with hikers or mountaineers.
