Pencell Pool

Last updated

Pencell Pool is a natural pool on the Murchison River in Mid West Western Australia. It is located on the Coolcalalaya Road about 8 kilometres east of Galena Bridge.

It is of geological interest because its steep cliffs expose excellent examples of Ordovician Tumblagooda Sandstone, containing trace fossils of Skolithos and probably Diplocraterion . The Tumblagooda Sandstone sits unconformably on gneiss of the 1100 Ma Northampton Metamorphic Complex, with a 200 m thick sequence exposed along the western bank of the pool. [1] [2]

The pool is considered to be in excellent condition, and is an important research site. It was nominated to the Register of the National Estate in 1992, but is not registered at present, being treated rather as an "Indicative Place". [3]

The Purnululu National Park is a World Heritage Site in the East Kimberley region of Western Australia. The 239,723-hectare (592,370-acre) national park is located approximately 300 kilometres (190 mi) south of Kununurra, with Halls Creek located to the south. Declared a World Heritage Site in 2003, the park was inscribed as follows:

...[is a] remote area managed as wilderness. It includes the Bungle Bungle Range, a spectacularly incised landscape of sculptured rocks which contains superlative examples of beehive-shaped karst sandstone rising 250 metres above the surrounding semi-arid savannah grasslands. Unique depositional processes and weathering have given these towers their spectacular black and orange banded appearance, formed by biological processes of cyanobacteria which serve to stabilise and protect the ancient sandstone formations. These outstanding examples of cone karst that have eroded over a period of 20 million years are of great beauty and exceptional geological interest.
