Columnar Basalt and Waterfall

R. Scott Ireland — Thu, 18 Apr 2013 23:17:16 +0000

Subject: Columnar Basalt and Waterfall
Location: Dverghamrar, Iceland
Notes: When the surface of a lava flow is cooled rapidly, hexagonal patterns (columnar basalt) may form perpendicular to the direction of flow.

Organ Pipes – Columnar Basalt

Subject: Basalt Columns at Reynisfjara Beach
Location: Reynisfjara, Iceland
Notes: When the surface of a lava flow is cooled rapidly, hexagonal patterns (columnar basalt) may form perpendicular to the flow direction. These “organ pipe” basalt columns are adjacent to the sea at the black volcanic sand beach of Reynisfjara, near Vik.

Subject: Columnar Basalt Rock Pattern
Location: Reynisfjara, Iceland
Notes: When the surface of a lava flow is cooled rapidly, hexagonal patterns (columnar basalt) may form perpendicular to the flow direction. This columnar basalt pattern is adjacent to the sea at the black volcanic sand beach of Reynisfjara, near Vik.

Subject: Columnar Basalt, Black Sand Beach and Sea Stacks
Location: Reynisfjara, Iceland

Subject: Eyjan – Asbyrgi Canyon
Location: Iceland
Notes: Asbyrgi Canyon is thought to have formed in under 3 days by an apocalyptic flood from a subglacial eruption (in this case from the Grimsvotn volcano), known as a Jokulhlaup.

Subject: Geothermal Steam Vents, looking toward Lake Myvatn and Reykjahlid
Location: Namafjall, Lake Myvatn area, Iceland
Notes: The fissure system at Namafjall straddles the Mid-Atlantic Ridge, with the North American tectonic plate on one side separating from the Eurasian plate on the other
