The Murrawijinie Caves - Nullarbor Plain, southern Australia
The Nullarbor Plain (Latin: nulla feminine of nullus 'no' and arbor 'tree') is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coastline with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock and occupies an area of ~200,000 km2. At its widest point, it stretches ~1,100 km from east to west across the border between South Australia and Western Australia (Wikipedia 2024).
The 'Nullarbor' contains widely scattered collapse dolines (collapsed caves) and several hundred caves; some large and extensive. The Murrawijinie Caves are dolines, typical of the Nullarbor's karst topography (Webb and James 2006). Karst topographies such as this are created when water seeps through large expanses of soluble rocks, such as limestone, riddling them with sinkholes and caves, like holes in Swiss cheese (Australian Geographic 2016).
Initial karst development probably occurred during the warm, seasonally wet climatic conditions of the Oligocene, when the withdrawal of the sea exposed the recently deposited Eocene limestone for over 10 m.y. During a wet phase ~5-3 mya, rivers extended across the karst plain and caves formed where they sank into the limestone. Shallower caves probably also formed at this time, perhaps associated with perched water tables (Webb and James 2006).

Well done 👍
Some excellent flying done there 😎

[@Mars2go]

Thanks 👍

I have never seen a drone flown inside a cave. I saw a Peter Gabriel concert in 94.

[@Mars2go]

Haha, I would have loved to see Peter Gabriel = legend muso.
Caves are pretty easy, as long as you have LOS, the bird will be fine.

@@Mars2go 5 years ago I filmed my girlfriend kayaking on a reservoir with a Phantom 3 and added Solsbury Hill for the sound track.

@@Kram_Farkel nice. Great track.
