About 30kms west of Marree, in a place called Alberrie Creek on the Oodnadatta Track is the Mutonia Sculpture Park. The sculptures appear to grow from the desert soil and you just have to pull over and explore.
The biggest and most imposing on the landscape is "Planehenge" - 2 silver Beechcraft Baron light planes standing upright with their tails buried in the ground. It's a 'what the' moment for sure!
This is a must stop experience. You'll love it. You enter via the Kombi gate and interact with these large art pieces.
The park itself is large and very spread out. Take a walk and check out Planehenge, Dream Catcher, Spinning Car, Time Tree and Big Dog.
Alberrie Creek is an old disused Ghan railway siding and if it weren't for artist Robin 'Mutoid' Cooke, the place would disappear forever. Robin is a former mechanic from Victoria. He came to Alberrie Creek for a uranium mining protest in 1997 and created his first art sculpture in the outback 3 years later. "Conceived and raised by Mutoid Waste Company to mark the passage of the Earth Dream Journey 28 May 2000" reads an inscription. He added a new artwork to the park each year.
