The Breadknife
The Breadknife is a long, narrow and tall extrusion of volcanic rock that dissects the ascent like some massive fossilised spine. Technically known as a dyke, it was formed some 13 million years ago as molten magma was forced up through a narrow crack in the rocks below the volcano. Once this molten rock cooled and solidified it formed a cast of the fissure and with the erosion of the surrounding softer rock the igneous wall remains 100 metres above the surrounding ground.
