Australia boasts a geoglyph that's larger than Peru's "Nazca Lines" and England's "White Horse". Called the "Marree Man", the pictograph measures 4.2 km tall by 2 km wide and is etched into a plateau near Marree. It depicts an Aboriginal warrior throwing a hunting stick and is so large that it can be viewed fully only from the air. "Marree Man" was discovered by a charter pilot in 1998 and, despite being the world's largest geoglyph, its origin remains a mystery.
