Reynisfjara Beach and Bassalt Columns

Depite the magnificent waterfalls, geysers and volcanoes, this was my favourite site on our Iceland tour in August 2015.
 An amazing, fantastic sight.

Columnar bassalt is formed when magma cools slowly and cracks into columns, usually hexagonal, as surface area dedreases.
The columns always stand perpendicular to the cooling surface and can be horizontal, spreading out from the centre, or vertical.
The varied forms of columns here are perhaps due to this being a cross-section of an ancient volcano.

A fantastic site.  The black-pebbled beach and the surf were great sights too.
The whole scene blew me away!!!
