Organ Pipes Valley Namibia A Geological Phenomena
Similar formation to Giants Causeway in Northern Island, but much better condition
In this area about 125 million years ago the continent of Gondwana was breaking up. In many
areas of Africa molten rock pushed up through the earth's surface. The shapes that formed here
are a natural wonder and there are areas where the side walls of the dyke are collapsing and individual columns can be viewed and studied close-up. The colors of the weathered rock are quite attractive under the correct sunlight conditions. Best time for photographs is mid morning or mid afternoon. If you're too early or too late there will be shadows cast over the
Getting There: This is a tricky one as you can drive past it owing to it not being properly sign posted. As you drive along the D3254 you will tend to be looking for the Burnt Mountain which is on the right hand side of the road. Just before you reach the mountain on your left hand side you can see a small stone having hand painted directions to the ORELLPYPE (Organ Pipes). There is a small car park just off the D3254 road and below is the small valley of the organ pipes in which the polygonal rock columns can be viewed.
Organ Pipes Valley Namibia: Geometry - Seen to be working:
As the molten rock pushed up through the earth's surface it began to cool from the outer edges of the intrusion - inwards. The movement of the remaining innermost magma was restricted to 'vertical movement only'. As it cooled and contracted the rock split vertically forming columns that have polygonal cross sections in accordance with geometric law. The resulting formation leaves no voids between the columns.
Polygons applicable to this type of phenomena are Triangles, Quadrilaterals and Hexagons. They can be regular or irregular polygons. In this case the sides of the neighboring columns will be of similar length and shape, and they can even be curved as can be seen in the above left photo.
One familiar example of a regular polygon being used in nature is the hexagon as used by bees when building their honeycombs.

Of Interest: A similar Geological Occurrence to the one in the Valley of the Organ Pipes can be seen at the Giant's Causeway in Northern Ireland.
