Coral Castle
One man single-handedly built Coral Castle in Homestead, Florida, over the course of 25 years. He worked on this art installation up until his death in 1951. No heavy or large machinery was used to make these rock fixtures. He cut, moved, and sculpted more than 1,100 tons of coral rock.
Blood Falls
It's not actually blood, but it sure looks like it! This mountain range in Antarctica looks like its spilling out blood when, in reality, it's spilling out iron deposits that oxidise once it reaches the surface. This is basically just a lot of natural rust!
