Fireclay Caverns
Fireclay Caverns are located in the heritage-listed Mount Morgan Mine site in Queensland, Australia.
The Fireclay Caverns were excavated by the Mount Morgan Mine to provide clay for its brickworks. Excavation of the caverns ceased when the mine brickworks were decommissioned. Erosion revealed dinosaur footprints on the cavern ceilings plus the caverns also became inhabited by a colony of bent-wing bats. Walkways and stairs have been constructed to provide access to the dinosaur footprints 〔(Queensland Government: Mines and Energy: Mount Morgan Mine Site Quarterly Update: April-June 2010 )〕 as part of the mine site tours.
== History ==
The Fireclay Caverns were excavated to supply clay to brickworks of the Mount Morgan Mine. Clay was mined from within the caverns by pick and shovel, then transferred by underground rail to a brickworks lower in the Mount Morgan Mine site. Excavation from the caverns ceased when their clay was no longer required by the mine.
