Nature's balancing act. Devils Marbles Conservation Reserve, Australia

These aren't your ordinary rocks! One of the oldest known religious locations, the Devils Marbles, holds significant value for Aboriginal Australians as an ancient sacred site. Today, the Devils Marbles Conservation Reserve—also called Karlu Karlu—in the Northern Territory of Australia preserves the collection of giant, round, gravity-defying boulders. These rocks are composed of granite, and their peculiar shape is the result of millions of years of weathering and erosion. One can explore the walking trails, gaining insights into the Aboriginal Dreamtime stories associated with the rocks. Whether you're a geology nerd or just a casual nature lover, embrace the minerals around you and rock on!
