Pencell Pool
Pencell Pool is a natural pool on the Murchison River (Western Australia), Murchison River in Mid West (Western Australia), Mid West Western Australia. It is located on the Coolcalalaya Road about 8 kilometres east of Galena, Western Australia, 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 Mya (unit), Ma Northampton Metamorphic Complex, with a 200 m thick sequence exposed along the western bank of the pool. 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".

Murchison River (Western Australia)
The Murchison River is the second longest river in Western Australia. It flows for about from the southern edge of the Robinson Ranges to the Indian Ocean at Kalbarri. The Murchison-Yalgar-Hope river system is the longest river system in Western Australia. It has a mean annual flow of 208 gigalitres, although in 2006, the peak year on record since 1967, flow was 1,806gigalitres. Basin The Murchison River basin covers an area of about in the Mid West region of Western Australia. It extends about inland from the Indian Ocean, onto the Yilgarn Craton east of Meekatharra and north of Sandstone. Rain generally falls in the upper basin during summer cyclones, so for much of the year the Murchison River does not flow, leaving a dry sandy river bed and intermittent permanent pools. The eastern reaches of the basin contain large chains of salt lakes, which flow only following rainfall. The drainage lines from these lakes merge to form the Murchison River about north-northea ...
