Volcanic basalt columns (organ piping) fallen from the cliff face

Australia 2015. Love my columnar basalt. Once again some detail from Sawn Rocks at Killarney Gap  in Mt Kaputar National Park near Narrabri, NSW.

Australia 2015. Detail and wide on the columnar basalt formations at “Sawn Rocks” or the “Organ Pipes” in Mt Kaputar National Park outside Narrabri, NSW. This has to be one of the best examples of columnar basalt I know of, and is unusual in that the upper levels have been left suspended by a process that is not entirely clear to me.

Sawn Rocks: Nature's Organ Pipes

Situated in the Mt Kaputar National Park, NSW, Australia is a towering face of trachyte columns, resembling organ pipes rising 40 metres high.

They are the result of slow and evenly cooled lava, which as it cooled shrunk slightly, causing jointing across several planes. At Sawn Rocks, the columns are mostly pentagonal in shape.

Mt. Kaputar is an extinct volcano, last active around 18 million years ago however, its past activity is still clearly visible today.
