Arkaroo

In the Dreaming of the Flinders Ranges, Arkaroo is narrated as a great ancestral serpent whose actions formed local topography and hydrology. Sources relate that Arkaroo drank the waters of Lake Frome, leaving it largely a salt pan, then moved west into the ranges where, 'heavily filled and tired', he retracted for a nap; by the length of his body he carved the valleys now known as the Gammon Ranges, and at each place he rested and released water he formed permanent waterholes such as Arkaroola Springs. The story functions as an etiological account linking named landscape features and place-names (Arkaroola Village, Arkaroo Creek, Arkaroo Rock) to ancestral action.

Accounts consistently describe Arkaroo simply as a 'serpent' or 'great snake' without detailed physical attributes. Sources emphasize scale by calling it a great or legendary snake and by mapping its corporeal length to landscape features: the reclining or retracting body is said to have carved valleys in the Gammon Ranges and its resting positions produced waterholes such as Arkaroola Springs. No coloration, scale patterning, or precise morphology is provided in the cited sources. (Wikipedia; Vulkathunha-Gammon Ranges NP; Odyssey Traveller)

Arkaroo's primary powers in the tradition are cosmogenic and landscape-forming: drinking entire water bodies (Lake Frome), excavating or carving valleys by its movement and repose in the mountains, and creating freshwater sites at places where it rested. Sources also record that Arkaroo was 'attacked by other mystic beasts,' implying interaction with other ancestral creatures and that such encounters had environmental consequences (release of water at rest sites). In contemporary cultural reading, natural phenomena such as rumblings in the ranges are attributed to the continuing presence or movements of Arkaroo, a claim contrasted in sources with scientific explanations of regional seismicity.
